Windows 2008 SP2 - Active Directory Server log in black screen

-

hi,
 
in our root domain, have 2 domain controllers installed.
 
server1: windows server 2008 sp2 / schema master , domain naming master, pdc
server2: windows server 2008 sp2 / global catalog
 
 
unfortunately, server2 on root domain has failed , had reinstall it.

dcpromo.exe , activation of global catalog role possible without issues.
after required reboot, logon on server2 "domain admin" account possible, saw error symbol on network icon on taskbar.
error message “unknown domain <domain>” or “not connected <domain>”

after second reboot, tried using "domain admin" account login , got see "access denied". then, blue screen changed black screen mouse cursor. no longer possible sing me in locally or via rdp, not save mode or command line.

remote connection event viewer on server2 shows me domain controller , global catalog installed without error , working fine.
possible connect dsa.exe domain changes here.


problem issue replicated server1, can't logon. server1 shows me same issue, black screen mouse cursor.
seems admins, service accounts , users don't have access anymore server services (wmi etc...).

thanks

hi,

i don't believe have encounter described, if can access event logs remote, there errors/warning in of logs system event log?

are these physical servers or virtual ones?

regards,

i have pc has power settings pushed out default domain policy in ad environment. of course on local machine "some settings managed system adminstrator". the machine temporarily no longer in contact domain controller (it's been physically moved , not on same network now) can't updated gpo settings. i believe if edit local group policy won't make difference because of group policy processing , precedence. since it's temporary away ad network, still want use settings of ad user. is there somewhere in registry stored can edit power plan manually until can sync domain? (i need prevent sleeping while plugged in - it's set 1 hour) thanks! allen crist i found site: http://gpsearch.azurewebsites.net/#7916 i able add policy to hkey_local_machine\software\policies\microsoft\power using specs found on site. looks solved issue. i'll report if didn't. thanks! allen crist ...
