Hi,

I (stupidly) forced one of my domain controllers to take over the Active Directory infrastructure master role when communications were down between that controller and the server with the infrastructure manager role.  It warned me but I clicked force, dooh!.

Now I have communications working again, the two domain controllers don't seem to have worked it out, they both think they have the Infrastructure Master role.  how can I force an update so they both have the same master defined?

Thanks

kiwiplan,

you seized the role? you will need to demote your false DC and re promote it

You can't have 2 infrastructure masters the fact that both machines now think they are infrastructure masters is causing issues. Jay70's suggestion that you demote on of the DCs and promote it again will cure the problem, however you might want to use the NTDSUTIL program first to identify and transfer any other FSMO roles which the rogue machine may have See http://support.microsoft.com/kb/234790 and http://support.microsoft.com/kb/255504

using utdsutil allows me to seize or transfer the role but it doesn't update the incorrect server.
So as much as I don't it I'm going to have to take James' advice and remove/read d the server.

Cheers Guys.
