Host Process Rundll32 Has Stopped Working in Windows Vista

[Beryl]

Everytime I open my Windows Security Alerts, I get this error....

"Windows Process (Rundll32) has stopped working"

I'm using the new Vista Home Premium. Anyone know a fix to this problem? I can't get in to the security centre at all. I've had Vista now for one week...since that time i've had to do system restore to correct other issues in it as well several times....

Any ideas or help would be greatly appreciated...:-)

I am missing XP really bad.

Here's a quick fix that might work for you. Go into to System>Advanced System Settings>Performance>Settings>Data Execution Prevention>Turn on DEP for all Programs and Services except those I select.

Now you must click add and navigate into the System32 folder. Now you need to select dllhost (which is COM Surrogate) and open it and choose ok to the warning. You'll see COM Surrogate appear with a check box selected.

Now you must do the same thing to add rundll32(which is Windows host process) from the System32 folder. You'll see Windows host process( Rundll32) appear with a check box selected after you choose ok to the warning.
Click ok to close out the Advanced Settings.
