I had several machines not checking into a new WSUS server. After some digging I discovered that after cloning machines from the same image that a registry key was preventing the machines from joining the WSUS server. You see, they all had the same SusClientID key and would compete for the connection to the server.
Create a .bat script and you can push this out with Altiris or add to a logon script.

1. Copy this script to a txt doc and save as a batch file.
2. Change this line to match your server path http://SERVERNAME HERE:8530
3. FYI: The number at the end of the server path above is a port number, this may not be needed for your implementation.
