I have been struggling with this problem for a while.
Can and expert guide me through this problem. This is a Windows 2000
Server with SP4. I have read many of the posts and tried all
suggestions but so far no success.
The Bits Service does not start and it doesn't seem to log any messages
in the event viewer.

this is what happened after typing net start bits
The Background Intelligent Transfer Service service is starting........

The Background Intelligent Transfer Service service could not be
started.
More help is available by typing NET HELPMSG 3523.

This is the error message when started it under Services.mmc
Error 1053: The service did not respond to the start or control request
in a timely fashion.
