Upstream server A. Down stream server B.
Initially A was getting updates from dodwsus. B was a replica of A. There was an issue with dodwsus and A was changed to download from Microsoft. B still replica of A. Synchronization fails when this is a replica is selected on server B. But if I uncheck this is a replica, synchronization works. Due to policies A could not connect to Microsoft catalog using wsus console to download specific updates. Server can connect to Microsoft catalog using wsus console. So I changed them around and made server B my upstream and server A my down stream. Server A can synchronize with server B, but when I select this is a replica synchronization fails.
Synchronization works both ways but fails when this is a replica is selected on either server. Any help would be appreciated. Thanks
