I am running Windows update an SBS 2008 box. The machine seems to download
and install 39 updates, then it fails with the message:

Some updated were not installed
Restart now to finish installing updates.
Succeded: 1 update
Failed: 38 updates
Error(s) found:
Code 80070718 Windows update encountered an unknown error.
Code 643 Windows update encountered an unknown error.

I started with needing 43 updates, and each time it installs only 1.
If I run it again, it will probably install 1 and tell me it failed to
install 37 others.

Please help.

Thanks!
