WSUS server does not show all the machines in the domain in the console.

It been few months and 400+ systems do not show in the console in WSUS server. it shows 4000+ machines but not these 400+. They are in the same domain and OS is also same.

Automatic update service is started and in client diag no issues are found. is there any other things i can check fo fix this issue.

    If you do  an RSoP on some of the missing clients, are they picking up the correct settings for the WSUS server?

    Do you clone your PCs? It may be a case of PCs being built with the same WSUS ID so multiple PCs will show as one client.

    I have a script - some consider it overkill but it cures a lot of WSUS client ills in one go.
