We've decided to set-up replica WSUS servers at all of our larger remote sites. I have a central server here at the main office with replicas at each location all looking to our server for their downloads.
However I'm seeing some odd behavior. 3 of the 4 sites think they need to download 9,000+ updates at 124GB total. 1 Site Thinks it only needs 388MB of downloads. The main server only has about 69GB of updates. Something is wrong here.
