Can't create System Restore point

[Stanley]

Hello everyone,

I just installed SP1 and all critical updates, and now
when I can not create a restore point. I am able to run
System restore, but when I select "Create a Restore
Point" and click next, I get the message that I can't
create a restore point and to reboot and run System
Restore again.

Any help would be greatly appreciated!

Cheers,
Stanley
