    Having problems replicating between 2 DCs. Just getting into server support so this is all pretty new to me so excuse me if I sound silly at any point but really want to resolve this problem. To note, this is an inherited set-up.
    DC1 (oxin-ic-cic-01.oxin-ic.co.uk), which is server 2003 and is the schema master, domain naming master, RID, PDC and infrastructure master. Also the DNS server.
    DC2 (ic-cic-ts-01.oxin-ic.co.uk) also server 2003 uses DC1 as DNS so just has active directory installed. Also has Terminal services installed but not set-up or in use, just has the role installed.
    DC3 (oxin-sp-01) server 2008 standard, is a sharepoint server. DC3 and DC2 replicate to one another OK, but DC1 the FSMO master does not replicate with anything.
    DC1 and DC2 are not replicated, or accepting a “replicate now” command. When I click “replicate now” on either I get the same error message.
    From DC2 “The following error occurred during the attempt to synchronize naming context oxin-ic.co.uk from domain controller OXIN-IC-CIC-01 to domain controller IC-CIC-TS-01:
    The naming context is in the process of being removed or is not replicated from the specified server.
    This operation will not continue.”
    And doing the same from DC1 I get the same message. The system log has a lot of kerberos erros in it of the following.
    The kerberos client received a KRB_AP_ERR_MODIFIED error from the server host/oxin-ic-cic-01.oxin-ic.co.uk. The target name used was DNS/oxin-ic-cic-01.oxin-ic.co.uk. This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server. Commonly, this is due to identically named machine accounts in the target realm (OXIN-IC.CO.UK), and the client realm. Please contact your system administrator.

    Im really tearing my hair out here, with no sense of direction in terms of what I should be looking from now and I’m hoping someone can direct me from the diagnostic results above. Its seems that DC2 and DC3 are more up to date than DC1 as well, as there are a couple of machines I added to the Domain a couple of months ago and they are not showing in AD Users and computers on DC1 but are on DC2 and DC3.
    Hope this thread isn't overkill but just wanted to provide as much info as possible to start with. Hoping I can crack this with some help from you guys. 
    Thanks in advance.

    Thank you, I had already resolved this issue before reading your response. I seized all roles onto DC2, dcpromo /forceremoval on DC1 and then re-installed AD and all is working again now.

    thanks.
