Root Certificates and Windows Mobile

Had a wierd week just past. My HTC Touch Dual 850 phone suddely stopped working. The symptom began with Active Sync not working. I discovered that everytime I hit sync on the phone, Active Sync would terminate. Rebooting didn’t fix the problem. I cleared the phone settings and started again. Still no luck. I found further symptoms. When I opened IE on the phone, I could browse to various web pages. When I tried to open a https page, IE would also terminate. Further testing revealed that this worked fine when working with Vodafone, or when plugged into the PC. However, I could not do this on the Telstra network. After getting to level 3 support, I was asked to try removing the proxy setting. This worked.
 
BUT…..
I now got a new error message stating that my nice new thrid party certificate was not valid. OWA and outlook Anywhere worked fine, just not Active Sync on Windows Mobile 6. Finally…. after 5 days of messing about, which included a reimage of the phone ROM image, I solved the problem.
 
Earlier, I recommended that we can use RapidSSL from www.ssldirect.com as a trusted certificate on SS2008. When contacting SSL Direct with this problem, they said that their RapidSSL certificate was not certified to work with mobiles. This was very unusual, since it had been working fine up to this point. The RapidSSL certificate uses a certificate issued by Equifax Secure Global eBusiness CA-1. Whenever I installed the certificate on WM, the certificate would be installed as an intermediate certificate. There is no utility to install this as a root certificate. However, I found a Equifax Secure Global eBusiness CA-1 root certificate on SSL Direct, which installed itself as a root certificate, and apparently, this passes the intermediate requests on like a proxy. Installing this certificate fixed the problem, although I do not recall having to do this when it was working earlier. Something to note down for the future. In the meantime, be careful.

Hi Boon,

I experienced pretty much the same thing with a Sony Ericsson p1i cell phone, that phone does have the same equitrac cert built in as HTC phones have, however not the correct version of it, so I downloaded this root cert and installed it, after that activesync worked no hassles.

Have not tried it with a HTC though, but I think it will work.

Remote Web Workplace (RWW) is not working after XP SP3 is installed

After Windows XP SP3 is installed, users have been unable to access RWW from their PCs. This is caused by the SP3 installation which disables the Terminal Services Client Control ActiveX applet.

To fix the issue, start Internet Explorer. Version 7 is assumed.
Go to Tools, then Internet Options.
Click on the Programs tab.
Click on the Manage AddOns button.
In the list, look for Microsoft Terminal Services Client Control. It will be disabled.
Select the control, then click on Enable.
Close, and restart Internet Explorer.

If this doesn’t work, have a look at the following site for more information – http://www.sbslinks.com/fixmyrww.htm

Screen Upside down (or sideways)

Here’s another oldie, but I still get calls on this regularly.
I happens predominantly with computers using windows XP and Intel or NVidia graphics adaptors.

To fix the problem, press CTRL-ALT-UP.
To turn it upside down again, press CTRL-ALT-DOWN. To turn things to the left, CTRL-ALT-LEFT, and to turn it right, CTRL-ALT-RIGHT.

One gotcha. If you had rebooted to PC to try and fix the problem, you might need to log in first, before the keys will work.

FYI. There are 5.3 million hits on this google seach – http://www.google.com/search?hl=en&safe=off&rls=com.microsoft%3Aen-us&q=screen+upside+down&btnG=Search

Server Reboots – When a power cycle is not enough

Had one of those problems today. The server had to be restarted. The client pressed the power button and held it for 5 seconds, because there was nothing on the screen. Then they turned the server on again. Nothing. Tried it a few times with no luck.

I got to the site and tried it too. No luck. Finally, I pulled the power cord out of the power supply. Plugged it back in after 10 seconds, and up came the server. Why? I don’t know…

How to change Terminal Server’s listening port

An oldie but goodie. I use this often – http://support.microsoft.com/kb/187623

Regedit.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp

Change the port number from Decimal 3389 to something else.

You will have to restart the server after this.

PS. To access Remote Desktop quickly, type mstsc -v:[server, IP, or net address] from a command prompt.

Getting rid of a Sync’ed server

Finally found an answer to a problem that had been bugging me for some time.
When a new server gets put into place, some workstations with XP Pro might have offline files configured. How do we get rid of these entries? It wasn’t enough to just delete the files. The PC kept wanting to look for the old server.

1. Open Up Windows Explorer. Tools. Folder Options. Offline Files. View Files. Ctrl-A to select all files. SHIFT-DEL to delete all offline files stored on the PC.
2. Regedit. HKCU\software\microsoft\windows\currentversion\netcache\. Locate and remove all entries pointing to the old server.
3. Do this for all users loggin on to the PC.

PS. Daniel Mundy added a comment on the previous blog site:
Or you can set the following registry key once, avoid having to log in as each user:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\NetCache
Key Name: FormatDatabase
Key Type: DWORD
Key Value: 1
