WORKAROUND
On Windows 2003 Server, make sure the NetworkService account has read access to the system drive. You can use the CACLS command to adjust the ACLs.
CAUSE
For Windows Server 2003 a possible cause is that the NetworkService user account does not have read access to root drive of system drive.
STATUS
Microsoft is currently investigating this issue.

I am getting the same error message but im running WSUS on W2K server not W2K3. I'm stuck, as all answers i can find are for W2K3. I have looked but the Network Service account does not exist on W2K.
Anyone out there got any ideas??????????
