I have read through all the other threads on connector upgrade errors and still have no answer.
I have changed permissions on the WHS Windows/Temp folder; uninstalled/deleted folders and registry keys, reinstalled from server:55000; reinstalled from the software share, reinstalled from a local copy.
Each time the install works, shows green on 'joining windows home server' but then fails on 'configuring computer backup' with no way past this. It's not a network issue as I can ping/remote desktop the server.
The client is W7 Pro with all the latest windows updates. I have two other W7 Pro machines with no problems.
I have also deleted the computer from the server but that did't help.
I am considering uninstalling the server update from January but don't want to as the other two clients are working and backing up ok.
