I have several Windows servers that the Automox agent reports and issue with the Windows update server.
Connectivity to Patch Source:
Windows Update Server
There is no problem with using Windows Update locally on the server. I had to resort to using it locally to patch this server. I had opened a support case on this and was told to contact Microsoft support. This response made no sense and I told the engineer that. I'm supposed to contact MS support and tell them there is an problem with Windows Update working on a server when it is working as expected.
