How Can I Tell if SUS is Working?

I've gone through all of the steps to install and use SUS, but I can't figure out if it is working. Some updates have been installed as evidenced by ADD/REMOVE PROGRAMS but not all of them. Also, it didn't happen at a time that I had selected.

  1. What IS supposed to happen at the scheduled time? I thought it should download and install necessary updates, so I should see something happening. I've set the time and then waited for it to pass and nothing happens, even though a reboot should be required. (Yes, WU is installed on my client (Win2k SP3), Updates have been approved, the server name is resolvable and the policy is being applied.)
     
  2. How does WU handle missed events? (i.e. If I set it to 2 AM and the computer isn't on, does it try again when the computer is turned on?)
     
  3. If multiple events require a reboot, does it chain them? or do them one at a time? or one each day? What happens? (i.e. do I have to dribble them out to prevent users from being locked out of their machines for 45 minutes.)

I have looked at the log files and event log and seen some evidence that it has talked to my test client, but nothing consistent has taken place.

The Windows Event Log on the client computer will post an event when updates are installed (or are ready for installation). If you are using the "forced install" setting (option 4 in the Group Policy) then the install will occur at the proper time and a message will inform the client computer that the machine will restart. This is quite reliable, once the policy is properly applied.

Also, you can determine some other things about timing from the '
C:\WINNT\WINDOWS UPDATE.LOG' file.  There's a good bit of information about the interaction with the SUS server in there.

And finally, by looking at the IIS logs on the SUS server, you will find the entire conversation between the client and SUS. The IIS logs are at '
C:\WINNT\SYSTEM32\LOGFILES\W3SVC1'.

In addition to the above, the following article also offers some advice on what to check:

The key to troubleshooting is reviewing the information in the logs, both on the client and on the server. Also, it is a bit easier to import the 'WUAU.ADM' admin template than it is to create your own registry entries which need to be perfect as far as capitalization goes and all that - 'GPEDIT.MSC' is the tool for that.
