Server 2008 AD Errors showing after running DCPROMO
Posted on 2010-08-17
I have Event ID's 1925 and 1645 showing in my error logs on a new 2008 server that I have just promoted on a 2003 network ready to demote old domain controllers.
Event 1925: The attempt to establish a replication link for the following writable directory failed.
The target account name is incorrect.
Event 1645: ADDS did not perform an authenticated RPC to another directory server because the SPN for the destination directory is not registered on the KDC domain controller than resolves the SPN.
Any advice would be appreciate as Ive spent several hours researching this issue with no luck... I suspect the issues are down to one DC and I'd demote it except I get 'target account name is incorrect' ...
I've spent most of the day checking / tidying up DNS which now seems to be fine.
