  • Issues with moving active directory

    Hi,

    We had some hardware issues with our server so we decided to replace it with another machine. We have small network of ~10 users.

    Old server was acting as domain controller (only one), dns, dhcp and exchange server.
    We installed new win 2003 server and exchange 2003 (running dcpromo on old server, ...) and also dns and dhcp services. We turned on 'global catalog' and all FSMO roles on the new server, and moved all exchange mailboxes over to the new server.
    This setup with two servers seems to be running without problems.

    When we turn off 'global catalog' option on old server we get fsmo check errors with 'dcdiag' util (Warning: DcGetDcName(GC_SERVER_REQUIRED) call failed, error 1355) - it can not find global catalog server - it's record in dns points to old server. We couldn't resolve that issue with manualy removing entries for the old server in the dns, nor with reseting registrations? with 'ipconfig /flushdns' and 'ipconfig /registerdns'.

    We have also tried demoting old server with dcpromo (?!) but it fails with message 'The specified domain either does not exist or cold not be contacted'.

    We can't find cause of our problems, thaough we found some issues with our previous tcpip configuration (domain suffix was incorrect in dns options). How can we fix those issues and demote old server as it has some hardware problems.

    TIA,
    Damir

    did you wait some time for replication? (after setting the GC and fsmo roles to the new server)

    otherwise, seize them with NTDSutil.

      I have tired waiting for replication of both gc and fsmo but the problem persists?

      here is the output of seizing operation of ntdsutil, new server is MIRKO, old server is STIPI:

      here is output of 'dcdiag /test:FsmoCheck /v':

      After turning off 'gc' for old server and waiting 15 minutes i get this:
