'Admin policy' broken on WM2003 !

'Admin Policy' is a little-known feature of Microsoft PocketPC that was built mainly for security-aware corporate customers. It allows one to lock a PocketPC device in a mode that no longer display a 'run' dialog, disallows the addition of external programs via ActiveSync or through Internet Explorer, disallows renaming of files to .exe and disallows remote changes to the registry through 'RapiRegMod'.
To be able to play with 'Admin Policy', on most PPCs one has to rename the registry value 'Redirect' in the registry at '\HKLM\Controlpanel\AdminPassword' to something else. Then go to 'Settings' / 'System' and look for the 'Policy' applet.
To enter the 'Secure Mode' the user has to enter a password, and the same password needs to be entered if the user is to leave again. The unicode representation of this password (0x0000 appended) is hashed using MD5 and placed in the binary value 'AdminInfo' in '\HKLM\Security\Policies\Shell' (on WM2003) or '\HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Shell' (on PPC2002).
However, they forgot to move the DWORD value 'NoExternalExes' (set to one when the Admin Policy is on) from the old to the new spot in the registry, and so the whole system just doesn't work on WM2003: you can still move binaries to the device and run them.
It still claims it works: it says:
Once enabled, users will not be able to download new programs via Pocket Internet Explorer, ActiveSync, or beaming to their mobile device. Users will not be able to rename programs to enable them to start on the device.

But that's Not True (tm) until you manually add the 'NoExternalExes' value.

ActiveSync over Air

Hi, my exchange is 2003 sp2. I can access /exchange and /oma fine on the public address but when i try to syn with activesync it just keeps prompting me for a correct password even tho the one i type is corrent!
Has anyone else had this with SP2 and Activesync. If i test the activeync folder in internet explorer i just get a 501.
Help please. I think i'm sooo close to push mail but something is not set correctly.

Does your certificate server name match the name of the server you put into the pda setup? Is you ssl server certificate publicly recognized as secure?

Public Name and cert match. If i use a PC i can access http://publicname/exchange or http://publicname/oma no worries. If i try to sync my JasJar with new rom all i get is password promt again and again. I think i must have to do something with the activesync folder in IIS but not sure what, event log indicates wrong password (error 529) but its the same ones used for OWA and OMA and thats fine!
Please help...

How to setup E-Mail Encryption (S/MIME)

Although PGP may be nice, the unfortunate fact is that it doesn't just "hook in" nicely to WM6 right now.
The track favored by the industrial giants is S/MIME, which is what Outlook and Netscape use. OpenSSL also includes the basic plumbing to do S/MIME stuff.
Let’s try to compile a simple step-by-step description with this thread, so as soon as it is complete we can create a wiki entry.
Step1: Setup Outlook utilize s/mine
Step1.1: Making a new X509 certificate
First, get and install the latest version of OpenSSL (if your OS doesn't already come with it). For M$ Windows you will find a installer here.
Next, you'll need to make a key pair so go to the bin folder and type:
% openssl genrsa -des3 -out keyfile 1024
This will make a key pair file. The private key will be encrypted with Triple DES. This means that anytime you do anything with the private key (like sign a message), you'll have to provide a passphrase (which you set at generation time). If you don't want to do this, then leave -des3 out, but just know that anyone who gets a copy of your key file can sign messages from you and read your encrypted mail.
To allow that everyone who received a signed email from you can verify the signature, you should create now a Certificate Signing Request, to get it signed by some root certificate, but this is optional, you can also create your own Certification Authority. But as long as the recipient has not imported your CA root certificate, one will be cluttered by warnings and error messages every time a signed and or encrypted email is displayed.
So I propose to get it signed by any common public CA. I choose
Thawte as an example as they offer the service for free. But you can choose any other you like.
So go sign up with Thawte's Freemail program and request a new certificate. At this point, go to the bottom of the form where it says "Developers of New Security Applications ONLY". Check the box that says "Paste in CSR Certificate Enrollment". Then click the button right below.
On the next screen there's probably nothing to do but hit "next>" when it asks about your name.
On the next screen there's probably nothing you should do but choose all of your e-mail addresses and hit "next>". Thawte advises that not all mail clients can handle having multiple e-mail addresses attached to a certificate, which means that if you send e-mail to someone using one of these clients, they may get a warning that the certificate doesn't match the message's From: line.
Same thing on the next screen.
On the next screen, accept the default extensions.
On the next screen, you'll see instructions telling you to make your certificate request, with a 16 character garbage string as the Common Name. At this point, you should go back to the shell window and do:
% openssl req -new -key keyfile
Answer all the questions that openssl asks, but be sure and paste in the 16 character garbage string Thawte gave you for the Common Name. Copy and paste the certificate request into the box on the Thawte form and hit "Next>".
Make sure everything looks ok on the last screen and hit "Finish".
A short time later, you should get an e-mail telling you your new certificate is done.
Go to the page (link) in the e-mail save it to a file in the openssl/bin folder.
The saved SPC file is a simply DER encoded PKCS#7 file containing the certificates.
Next, type:
openssl pkcs7 -print_certs -inform DER -out certs.pem -in file (where file is the name of the file with the PKCS7 stuff)
You should get out a bunch of certificates. You'll need to look at the text above each one to find the one that is your certificate. The rest are part of Thawte's Certifying Authority. It turns out that if you want your messages to verify correctly, you must also include Thawte's intermediate CA key.
There should be 3 certificates. The file certs.pem will then contain all the certificates in PEM form, you can manually cut and paste them. The one whose identity is your e-mail address is your certificate. The one whose subject and issue are identical is the Thawte CA root. You won't need that one, since we'll include it in the trusted root file later if it is not already there. The 3rd one will have the CA root as the issuer and something else as the subject (which will be the same as the issuer of your certificate). You need to save that certificate as an additional certificate for signing. We'll refer to the file containing this cert as othercert.
When you're done with all of that the pieces you need to keep are the key file you generated at the beginning (remembering the passphrase, if you set one), the intermediate cert between the Thawte CA root and your cert, and the certificate chunk for your e-mail address you got out of the last step. You're now ready to use S/MIME!
Step1.2: Importing in OUTLOOK
Outlook uses the pkcs12 format. OpenSSL can import and export certificates and private keys so that you can use the same cert and key pair on all your mail clients. To move a keypair and cert from OpenSSL to Outlook, you need to export it:
% openssl pkcs12 -export -inkey keyfile -certfile othercertfile -in certfile -out mycert.p12
This will ask you for a passphrase. This phrase locks the .p12 file. Outlook will ask this passphrase later.
Now open Outlook and go to Extras and open something called like Thrust center (I just have a German version so I can just guess).
Go to Email Security and click on Import, select your p12 file, enter your passphrase and click on OK.
In the next window you have the option the change the security level, medium means it will ask just for your permission, high it will additional ask for a passphrase, which will be defined if selected (not the same as used for protecting the keys).
On the same page section secure email (or something like that) you can change the settings concerning ciphering and signing algorithm.
You should choose for signing not MD5 as it is considered as broken, better is SHA1 even if this one is something like semi-broken.
Further you should prefer strong algorithm for instance 3DES instead of DES.
Select S/mime as format and give the settings a name before saving.
Now you are ready to use s/mime for signing and encrypting!
Step2: WM 6
Next step would be to import it in pocket outlook by just copy it to the Hermes and click on it.

I ll be honest, I didn't read your entire post
Just wanted to point out that in order to send an encrypted email to someone, you need to have his public key. Those keys are usually stored in a corporate directory, which need to be accessed in order to send the mail.

Thanks for your comment!

This is quit clear but for simply signing my own mail, just my privat key is required. As long as this is not working, encryption will also not work.
So the main problem is that Outlook is matching the certificate to email account, so most likely something with the certificate contained information
seems to be wrong...

Just for the records - as it seems I just soliloquise:
So I managed to get it working with Outlook!
I also successfully imported the same p12 certificate on my hermes.
For Pop3/SMTP accounts in WM6:
Receiving encrypted mails is working, the automatic s/mime decryption works fine.
But sending: under message options of a new email, encryption and signing is disabled !?!
Same for my synced outlook folder.
Could that be an issue with WMXL v0.21 ??
Maybe I should take BLACK 2.0 for a spin - it seems to be newer...
Or is s/mime encryption/signing only supported for exchange accounts?

... an other thing (outlook releated)
- please check the level of thrust for your own as well for imported certs
if the trustlevel is not set correctly outlook will refuse it (error: something
like certificate is invalid) - normaly that means a CA is missing the sequence
of signing CAs from the ROOT CA to the personal certificate
- If you receive a signed email: if you click left on the senders name and
select add to contects the cert is added to the new contact as well, as
soon as you save it, and the contact already exists select update.
Maybe this is the reason why using s/mime on WM6 is not supported as the contact database is not storing any certs ?!?
So its only working together with Exchange?

Hi,
I use WM 6.1 on my Hermes (CRCs stable version) and want to use e-mail encryption.
But it is not possible. Import of the private key was OK, now I tried to send a message to a user with a public key in GAL, but failure is "Error Crtifcates missing".
So I import the private key to my contact, but same failure.
Why does the device not find the public keys?

You need to import the certificate/public key of the recipient, also check the Key Usage extensions within the certificate, if they dont have the correct ones for e-mail encryption then your stuffed.

Answer find :
Sadly, Microsoft decided to not support S/MIME with SMTP, the Internet industry standard for e-mail. If your company or ISP uses another mail server than Exchange you will not be able to use the features "Encrypt message" and "Sign message" in Windows Mobile's "Messaging" application. The option "Security" is ghosted. This is clearly an example of vendor lock-in. It is an attempt by Microsoft to lock Windows Mobile users into Exchange and their other product offerings. I cannot think of a technical reason why Microsoft could not support SMTP for secure e-mail. Storing certificates on mobile devices takes valuable memory, but most certificates are only 1-2 KB. The least they could have done is use open standards such as LDAP for looking up certificates of recipients. (There is a "Check Names" option in WM6 where you can lookup names in an online server but I don't know if that means LDAP and if certificates are actually checked).

S620 WM6 Proxy login

I have my S620 (WM6) connected via WiFi to my laptop, and that's connected to my work network which uses a proxy to connect to the internet. What happened is that I entered the proxy password incorrectly when prompted by IE, and chose the Save Password option. So now each time I try to open a page I get the message "The user name or password is incorrect. Verify that CAPS LOCK......". Problem is I can't seem to find a way to delete the cached password, and the registry key mentioned in this link does not exist: http://thinkabdul.com/2006/04/25/deleting-cachedsaved-passwords-in-pocket-internet-explorer/
Any ideas?

Exchange Problems! 0x800072F17

I really didn't want to post this, honest. I have searched xda. I have searched the web. I have found other threads. I have followed the suggestions. But, it seems that my exgirlfriend may have been right, I'm an idiot.
I can't get my Hermes to connect to my office exchange server. The settings on my end are correct, the issue is on my office's end.
When I sync I get an error and support code 0x80072F17. I know that it's a certificate error.
IT is not going to help me on this one, so I'm on my own. I have tried to manually import the certificate. Didn't work. I tried making a regedit I found on another thread. Didn't work. I tried combinations of various settings. I only time I don't get an error code is when my device begins to endlessly prompt me for my password.
I'm sorry to post, but it's my last option. Does anyone have any work arounds for this error? Is there a way to have my device ignore the certificates? Is there anyone out there that can help??

There must be some way. My colleagues, both of them with HTC Trinity's, original WM5 roms came across this error when the certificate on our Outlook Web Access was about to expire. Me, however, with my HTC TyTN WM6 never got this issue. I'm not sure why. I know I've installed a couple of cert cabs, the one they call sdkcerts.cab and one more. Search for that cab and see if it helps. I always figured it made the device accept non signed software but maybe it helps for these kinds of issues as well.

You just must set correct date and time for you phone and try again.

I'll try and give you a hand...
First off, you need to know a few things to set this up.
(1) The FQDN of you company used to access the OWA (Outlook Web Access), for example, mail.mycompany.com/exchange
(2) The NetBIOS name of your local domain at your office (Right click the My Computer icon on your office pc and select Computer Name and note the Domain. If your IT dept did it the recomended way it'll have a .local extension, for instance, lawoffice.local. You'll use just the domain name without the extension, ie: lawoffice. (without the period, LOL)
(3) I absolutely never use my PC to configure my ActiveSync on my devices, just to initailly copy the certificate to the Storage Card.
Two ways to do the certificate. First is the method I always used until I discovered the second method, which is in my sig.
(BTW, substitute YOUR FQDN for mine, duhh! )
(1) Install the certificate on your PC by going to the FQDN of your OWA in Internet Explorer 7 on your PC, not your PDA (XP is much easier, Vista is quite difficult to do this)
For example, open IE7 and put mail.mycompany.com/exchange in the address bar. You should initially get a "There is a problem with this website's security certificate" error, click on "Continue to this Website" Now, next to the address bar at the top you'll see Certificate Error", click it, View, Install, Next, Next, Finish, Yes. Then you'll see "The import was sucessful" <damn, that took a while!)
Close IE 7 completely and reopen it, put "mail.mydomain.com/exchange" in the address bar and you'll go straight to the OWA page, meaning that your import WAS sucessful, yipee!
(2) Click on Start, Run and type "mmc" and OK. This opens the Microsoft Management Console and you'll see Console1 at the top. File, Add/Remove Snap-In, Add, Certificates, Finish, Close, OK. Now expand Certificates, Trusted Root Certification Authorities, Certificates. Find YOUR certificate in the list. Right click, All Task, Export, Next, DER encoded binary, Next, File name. I use c:\mail.mydomain.com so that I can find it easily. Now finish and you'll get the Export was sucessful message.
(3) Connect to your PDA via ActiveSync as a guest, kill your partnership if it exists, you don't need it), copy the cert to your Storage Card and execute it from there.
Now disconnect youR PDA AND open ActiveSync. Server address is the FQDN of you company without the /exchange, for example, mail.mycompany.com. Leave the check mark on the SSL. Next put your user name, password and the NetBIOS name of your domain. The configure you options for the number of days to sync, etc.
That's it!
Now... once you do that and it works, follow this thread, Auto-provisioning POP3 or Exchange mail via UC Mini how-to.
so you can create a cab to do this automatically!

I had this problem before.
For me, it was due to the fact that I installed CESTAR and it messed up my certs. Unintalling CESTAR won't fix it. You got to reload the rom.
From there, I used Leies' Chinese character support which is free and doesn't mess up the certs.

SOLVED
I have been at this issue for over 2 days now, dealing with the error 0x800072f17. About 5 min ago i fixed it. After narrowing the problem down to a certificate error i then proceeded to look at the certificates. There were two in the certificate store (personal) and both were self signed.
One was XXXX (server name) and the other was XXXX(company name) CA.
The server name one had expired. Seeing as how it is self signed, i had our it admin renew it. He forgot to re-assign it to the outlook web access, so i did it myself in the Internet Information Services console on the server.
This had solved only 1/2 of the problem.
The certificate was assigned to the exchange server, not the OWA web site. After discovering that i could not change the issued to name, or create a new certificate (not an admin) i decided to change the activesync settings to sync the INTERNAL OWA address, which is servername.internaldomain.externaldomain.com (this had not previously worked due to the expired certificate)
Now i have a fully functioning push email system.
Nearly all done without admin permissions.
Whilst im new to this site, feel free to pm me about it.
Solving this is the most satisfying thing i have done this year lol.

But does this allow you to get/check email from outside your location? Or do you have to establish a VPN first?
