Hello,this my situation (virtual nt4 domain):
srv1 PDC NT4 SP6 (DHCP,WINS)
srv2 BDC NT4 SP6
srv3 MEMBER SERVER WIN2K3 R2
I Execute these actions:
1 I put off-line SRV2
2 I upgrade srv1 to win2k3
3 I Install AD whit an active directory integrated zone
4 I Autorize the DHCP
5 I promote srv3
6 I put on-line srv2 (ex PDC)
7 I upgrade srv2 to win2k3
8 I try to promote srv2 but there is this error:
THE RPC SERVER IN UNAVAILABLE
In the event viewer there is this message:
NETLOGON ID 5805 THE SESSION SETUP FROM THE COMPUTER FAILED TO AUTHENTICATE – ACCESS IS DENIED
I presume there is not the secure channel from srv2 and the domain.
In need to upgrade srv2 because is an application/db server.
Where is the mistake?
What I have to do before to upgrade or promote a nt4 pdc after a domain upgrade?
Thanks in advance.
