Windows Server 2008 renamed to minwinpc after windows update restart

after installing recent batch of updates windows server 2008 machine, cannot logon after restart.

the problem with the sbs second server which runs windows server 2008 64 bit on physical box as a secondary dc and runs a sql server 2008 line of business application.

the sbs server runs virtual system on hyper v physical box. network, primary dc, exchange etc work fine.

all pcs in network run windows 7 professional , log on them not problem.

the problem second server returns error (5) access denied when trying log on machine remotely. interactive logon returns username or password not recognised. logging onto local machine returns "unable o logon - attempt made logon, network logon service not started"

pinging ip address of problem server works ok sending shutdown /m ip address -r -f  instruction using command prompt sbs primary server, however, sending shutdown /m \\computername -r -f returns (5) access denied error.

browsing network lists name of problem server minwinpc. can browse shared folders on minwinpc problem server.

i having problems logging on in safe mode or in safe mode cmd prompt.

i going on site tomorrow attempt recovery. have advice need logged on again , reconnect server network. able recovery console using windows server installation disk.

hi meinolf,

i have decided simplest solution reinstall windows server 2008, but time not dc, install sql server , restore sql server backups. halfway through doing now. i have no doubt solution coud have been found take long , client becoming agitated.

thanks advice.
