Getting an error trying to install Exchange 2010
"Setup encountered a problem while validating the state of the Active Directory. an active Directory error x51 occurred when trying to check suitability server <mydomain controller> error the active directory response the LDAP Server is unavailable"
I've installed a new Windows 2008 R2 Domain controller... moved all the fsmos, made it a GC... and now my Exchange 2010 install will not seem to find the new Windows 2008 Domain controller?
