Replicating servers issue
Hi,
I have 3 servers in the domain, MBBS (2008), PPMC03 (2008) and PPMC01 (2003), i have recently demoted PPMC01 having first transferred the roles to MBBS. In AD Sites and Services there are 2 sites MBBS & PPMC01 are in Site1 and PPMC03 is in Site2.
On MBBS, AD Sites and Services Site1 is showing MBBS replicating with PPMC03 and PPMC01 is there but without any NTDS settings, which is right. In Site2 PPMC03 is showing as replicating with PPMC01 which isnt right, it should be MBBS. On MBBS in ADUC PPMC01 is listed as a member server not a DC which is right.
On PPMC03, AD Sites and Services Site1 is showing MBBS replicating with PPMC01and PPMC01 is also there with NTDS settings, in Site2 PPMC03 is showing as replicating with PPMC01. On PPMC03 in ADUC PPMC01 is still listed as a DC which isnt right.
It seems that replication isnt working between MBBS and PPMC03 for some reason.
Any help would be very gratefully received...
Thanks
Andrew

how many replication groups have you created?
Run repadmin /showrepl and dcdiag /v to identify where replication is stuck
Run netdom Query fsmo on all domain controllers and ensure that FSMO placement is showing same on all DCs
Manually check if remaining DCs are replicating with each other properly thru AD sites and services
If here you get problem, check all DC related DNS records on all domain controllers
This includes, NS, Host(A), CNAME, PTR etc
Check under _msdcs.domain.com zone if CNMAE records are resolving to correct DC by pinging CNAME
Try to run metadata cleanup and remove the server you already demoted from AD metadata
Then force AD replication and see if it removes ntds settings from demoted DC in AD sites and services

Hi, netdom query fsmo is correct on both DC's.
DNS seems to be all ok, i can ping the fqdn of both servers in either direction.
Can I simply change it in Sites and Services on PPMC03 so that PPMC03’s replication partner is MBBS rather than PPMC01 – you seem to be able to do this in the properties of the NTDS settings of PPMC03 although it does come up with a warning that changing it will ‘mark the connection as not automatically generated’?
