Rob hit another issue with his SBS 2011 Essentials migration from SBS 2003:  “I couldn’t connect this one workstation to the network; the ClientDeploy log showed the error as InvalidOwnerOfMachine.  The problem is fully described at

The log file showed the following:

[2108] 110913.145924.7363: ClientSetup: Entering JoinNetworkTask.Run
[2108] 110913.145924.7363: ClientSetup: Network Join Client to Server: ClientComputerName=LABDELLD610-2 ServerName=ALPHA

Their solution didn’t work for me, however.  The only way I could get the Connect Computer wizard to successfully run was to use the domain admin account when the wizard asked for network name and password.  After the wizard completed I restarted and logged in as the correct user, and all was well.

    This is expected behaviour, just not well documented.
