Hi Ste78564
System Restore can be controlled via Group Policy editor in
the addtional Administrative Tools for system administrators.
If not already installed, You may need to extract AdminPak.MSI from
SP2 or SP3 or aternatively, get it from the i386 folder on a Windows
Server 2003 setup disk. Install AdminPak.MSI (Double Click) and a
whole lot more items are added to your Administrative Tools. The
one you want does not have an Icon so, In the run box type:-
"GPEdit.MSC"
Navigate to:-
Local Computer Policy
Computer Configuration
Administrative Templates
System
System Restore
There you will find the keys
Turn off Sytem Restore
Turn off Configuration
Both should read "Not configured" in an untouched system.
