  • Numerous errors in DCDIAG

    Back story: Sage MAS200 consultant needed a Active Directory free server to do their thing. I wanted to virtualize the Active directory server for some time anyway and used it as an excuse.

    Physical server: ARBSVR1
    Hyper-V Servers: ARBDC01, ARBDC02

    I installed Hyper-V in Test Server, installed Server 2008 x86. Installed AD role and did the dcpromo, no errors so far, only a FrsEvent error with a SYSVOL replication problem that was corrected after a log clear and a reboot. I then created a second Hyper-V Server 2008 x86 with AD and did dcpromo. So far so good.

    When I ran dcpromo on the original physical server it all went to hell. The Server didn't demote successfully and left a mess in DNS. The roles (RID,FSMO,etc) were assigned to ARBDC02 but ARBDC01 still sees ARVSVR1 as the role holder. Not I get a [email protected] load of errors in DCDIAG, DNS and SYSVOL is not replicating.

    After 1 hour of verifying DNS in both servers and adding the proper entries and removing the ARBSVR1 records I'm still having problems and fresh out of ideas.

    Links to DC results (too much characters and cant link yet) Copy paste in new tab:


    When trying to access the Schema from ARBDC01 i get "The list of Domain Controllers for domain xxx.local is unavailable because: Logon failure: unknown user name or bad password

    I'm loged on as the administrator, the list is visible from ARBDC02...

    EDIT 2:

    Added a third DC, transferred all of the roles over to the third DC. While demoting ARBDC01 i got this error:

    Thyere are no more endpoints available from the endpoint mapper reffering to ARBSVR2 and not the new dc

    Netdom query fsmo reports the correct values on all 3 servers. I would like to demote both arbdc01 and dc02 and just maintain the single new dc
