Virtual Server: Can't connect

Client can't connect to a Virtual Server PC session - but I can see it is in a running state on the server. The network is disconnected on the Guest OS... The user can't connect because the guest OS can't connect to the network adapter resource on the host...

Errors in Event Viewer -> Virtual Server Event Log:

Something has happened to the credentials under which the Virtual Server Guest OS is running? It's been working fine for a year now... and no one has touched this set up except myself when I set it up. Except for Windows Update... but Windows Update is not set to run on this machine for that very reason...

Those message above have been popping up all year too... but never affected it in this way before...

Loading up Internet Explorer ... Virtual Server 2005 R2 Master Status page...

Virtual Machines -> Configure -> ... leads me to the MachineName Status and Configuration page, where under General Properties, I can select: "Run virtual machine under the following user account:" and enter new credentials... Let 's see if that stops it ... (and a reboot - which would probably clear up the network glitch anyway...)
