Three servers in WSUS are acting strange. I have three servers, each named server1, server2, and server3. I can get one of them to check in with WSUS, but not the other two, and they are trading places. I can get 1 to check in, and then when I get 2 to check in, 1 disappears. It seems I can only get one of the three to check in. I have had each of them, at one time or another showing in WSUS, but the other two not. I can restart services and force a checkin, but I can only get one server of the three to check in at a time.
I have verified the GP, verified DNS, made sure the IPs are all different. I just can't get more than one of the three to check in.
Anyone seen this?
