What does this error event mean? Faulting application explorer.exe, version 6.0.3790.3959, faulting module explorer.exe, version 6.0.3790.3959, fault address 0x000030d8.

1.Do you have all sp's and patches installed.

2.Do you have mcafee installed, if yes
Try adding frameworkservice.exe to the Windows DEP exception list. This worked for me with another app that started to break only after installing Windows 2003 SP2. (Reinstalling the app did not help, but tried that first.)

to do this:

1. From the Start menu load the Control Panel and choose the System applet.
2. From the Advanced tab, click the Settings button under the Performance group.
3. Change to the Data Execution Prevention tab.  
4. Enable Turn on DEP for all programs and services except those I select: radio button.  
5. Click the Add button and from the dialog box browse and find frameworkservice.exe.
7. Click the Apply and OK buttons to apply the changes.
8. Restart the macafee services (or reboot the server and that will restart everything.)

I have Synmatec Enterprise 10.1.5 client installed on my server.  The explorer process is working and the error shows up only once.
I am not sure what caused it. I am running a virus scan now.  

A repair to Explorer could be as easy as running, (at the command prompt), SFC /scannow. That checks the versions to make sure you are on the current version and that the data isn't corrupt for many microsoft critical components.

Oh, my advice is redundant. Looks like sk_raja_raja had that covered. Sorry about that.
