This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
We have been running WSUS fine for some years now. In December, when we installed the latest Windows updates we restarted the server and since then, no client has reported in.
WSUS is working, we can see the last contact date updating and if we release a new patch clients are pulling them down, we just cant see the Reported status and hence cant get a view as to how up to date we are.
We run WAM from AJTEK and that seems fine and we have gone through the recommended documentation from AjTek several times and everything looks right its just we are not seen status, on anything.
I've read suggestions of re-indexing the database but wouldn't know how to do this or if its even the correct course of action. Any help appreciated.
