Here's my fix. a blog by Robert Kelly

First, let me say… I get about 10 to 20 unique hits on this post every day. We are not alone! Below, I describe a fix to the relationship. But I want to know THE CAUSE of the broken relationship! If you can help, please post a comment. -Thank you

OK, now I’ve got it on Windows 7!
Win7 has been running flawlessly for about three months. I was in the middle of testing various Antivirus solutions… I uninstalled Microsoft Security Essentials, and attempted to install Symantec Endpoint Protection. The setup cursed me, saying a previous operation required a reboot before I could install SEP. I rebooted, logged in, and was presented with a “Temporary Profile” error. I rebooted and the Log in gave me, “The security database on the server does not have a computer account for this workstation trust relationship”

Now, I know from previous experience (below) I could disconnect from the network (Cable and WiFi) and fix it like I did in Vista. But this time I got a quick fix with F8, Safe Mode (without network), System Restore to prior to Microsoft Security Essentials uninstall and all was good.

Some info I liked from a TechNet post:
“First some basics you most likely already know.
1. Computers are security principals just like users
2. Computers authenticate to the domain on startup
3. Computers change their password every 30 days by default
4. Restore Points restore the computer password present at the time of the restore point
5. If the local password and the domain password are not the same the computer must re-join the domain”

Older notes:

Additional note… I have had it! Goodbye Vista. Hello Windows 7. I got this error AGAIN on my desktop. I didn’t fix it this time. I moved directly to Windows 7. Now, the three machines that were running Vista are now on 7. Date 11/19/2009

Problem: The Vista user can log onto the machine with cached credentials (NIC disconnected and WiFi off), but not when connected to the LAN. ERR, It worked for the last year, just fine. Oh well…

You may also get this error: ”The security database on the server does not have a computer account for this workstation trust relationship.”

As the error indicates, the relationship between the client/server is broken. Let’s fix the relationship.

Kill and rejoin the Domain… (with PC rename in between)
On the DC:
Delete the offending Computer Account that resides in Active Directory.
Delete the Computer’s IP Lease(s) in DHCP
On the client (with no connection to LAN):
Log onto the local machine (not the Domain) as an Admin.
Unjoin the Domain by joining a “TEMP” workgroup. Reboot required. Log into TEMP workgroup as the Admin.
Rename the Computer. Reboot required.
Log into the Local Machine, now rejoin the Domain. Reboot required. Login into the Domain.
Test network access and life is good. The Computer exists in AD and DHCP.
Rename the Computer back to what I originally wanted. Reboot required.
Test network access and life is still good. The new Computer name is in AD and DHCP, as expected.

Come on people, this post gets tons of views. Give me some feedback!

Windows XP SP3. Can’t get Windows Firewall to fire up. I get “Windows cannot start the Windows Firewall/Internet Connection Sharing (ICS) service.” and Windows Firewall/Internet Connection Sharing (ICS) is displayed in the Services list, but I cannot start this service.

Here’s the fix:
From http://support.microsoft.com/kb/920074

Call the “Setup API InstallHinfSection” function to install Windows Firewall

To install Windows Firewall, follow these steps:

1. Click Start, click Run, type cmd, and then click OK.
2. At the command prompt, type the following command line, and then press ENTER:
   Rundll32 setupapi,InstallHinfSection Ndi-Steelhead 132 %windir%\inf\netrass.inf
3. Restart Windows,
4. Click Start, click Run, type cmd, and then click OK.
5. At the command prompt, type the following command, and then press ENTER:
   Netsh firewall reset
6. Click Start, click Run, type firewall.cpl, and then press ENTER. In the Windows Firewall dialog box, click On (recommended), and then click OK.

Still not working…

Then from http://forum.oscr.arizona.edu/showthread.php?t=2284

1. From the Command Prompt, enter:

netsh winsock reset

2. After receiving a confirmation, reboot

I can start the service and firewall now.

Symptom: Shortly after joining my WiFi network, it reverts back to the 3G network and has “forgotten” the WiFi password I gave it.

Solution: Go to Settings, General, Reset, Reset Network Settings and confirm. Rejoin your WiFi and all will be good.

Note: I have also read that some iPhones struggle if you have disabled your SSID Broadcast.

You install an automatic update for Microsoft Office Word 2007 on a Windows Vista (or Windows 7) -based computer and then restart the computer. If Word 2007 was running when the computer was restarted, you experience one or more of the following symptoms:

• The mouse does not work when you use Word.
• You cannot open a Word document from the Search window in Windows Vista.
• You cannot open a Word document from Windows Desktop Search.
• Word crashes when you try to start or exit Word.
• Word crashes when you open the Open dialog box.
• Word crashes when you save a document.
• Word crashes when you close a document.

To resolve this problem, delete the HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Word\Data registry subkey. Close regedit and start Word.
