I have a Windows 2008 server which is part supported by another company who also installed it.
Since it was installed the WSUS console on the server has never showed all clients. At the moment it is only showing 15 and there are more than 100 machines on the system. They did try reinstalling WSUS but it still is not shoing all clients.
They have said this is normal for WSUS and it is unreliable. Is this normal, or is this a known issue with a fix or should I be harrasing them to get it working correctly?
