Server service stops automatically in 2008 server

We also have encountered the same problem here in our Windows Server 2003. For the meantime we have temporary solutions by setting the Recovery to "Restart the Service". By doing this:

1. Go to Administrative Tools - Services
2. Right Click "Computer Browser" then Properties
3. Click on the Recovery tab, set the following:
First Failure = Restart the the Service
Second Failure = Restart the the Service
Subsequent Failures = Restart the the Service
Reset Fail count After = 120
Restart Service after = 0
4. Click Ok
