Hello,

I must make a trust between 2 domains but we have domain controllers with the same name in both domains. So we have troubles with DFS and GPO.
In fact, Microsoft use both FQDN and netbios so it find dc1.domaina.local in q first time and dc1 in a second time but it get dc1.domainb.local.
Can I disable the netbios search, force search with FQDN or I must rename the dc ?

Thanks

Best regards,

Might be easiest just to rename a DC on one side with NetDom.

While NetDom will work, there may be other issues that you need to look at.  For instance, if you had hard-coded any DSAccess domain controllers in the "Directory Access" tab within the server properties in Exchange System Manager, you would have to redo the settings (my memory of Exchange is fuzzy so there are likely other areas - YMMV).  Also, there may likely be issues with LDAP queries, certificates, etc.  
The rename is easy, the collateral issues are where you will spend your time.
