SUS – W2k SP4 for End users

I have an SUS server setup so that all my client pcs point to the SUS server to get critical updates. I’ve approved Windows 2000 Service Pack 4 Network Install for IT Professionals.

However none of the clients pick up this install. If I check the local pcs they are looking for “windows 2000 Service Pack 4 Express Install for End Users”

Any suggestions?
