Yes, SP1 is installed.
Yes, I can manually install updates.
I do not see that any updates were released in the past 24 hrs, so there is nothing I know of that I can do now to test what I've done so far. Any ideas?
An error number I researched yesterday when following the troubleshooting tips was 80246007. Some other recent ones are C355 and C0000135.
No, I had not checked out the Event Viewer. In doing so now, I see a lot of Bonjour Service, SideBySide, Tivo Transfer, ESENT, Event System, User Profile Service, VSS, etc. errors. 31,680 total!! I'm in over my head here as far as what is related. Here's one I see a lot that might be related -- CAPI2 (Event ID 4107, OpCode Info). And this? gupdate (Event ID 0, OpCode is blank, source code... ??? is that the gupdate?).
