We have 4 WSUS servers. One is the main server and the other 3 are downstream servers. We are having computers disappear from the upstream servers groups but remain visable on the downstream server in the correct groups. We have remove the computers from WSUS and when they reported again they were in the correct spot on all server but them a few houors later they disappeared from the upstream server again.
Any ideas why this would happen and how to fix it.
Thanks
