Hi all,

My colleague just managed to build a new server and join it to the domain as the same host name. This has just knocked the existing server off the domain and I cannot log on to the server as the local administrator either.

2008 server

Any ideas?

Are they DCs?  Remove one of them from the network via cable first.  Hope it wasn't a DC and delete the second entry from AD servers group.  If it was a DC you could be subjected to repeated DNS, authentication issues, GPOs updating and more.

okay then you should just be able to unjoin each from domain, remove from AD and the rejoin each to domain.  Keep static IP directly coorelated with the correct server

Why would the domain allow someone to hound a host that already exists? Surely that's asking for trouble?

they always have, just like that have always let you introduce duplicate IPs to the environment.  They figure that you know what you are doing being the end all.
