Recently I've done
some work for the company rebuilding the DC's for concerns of naming conventions
including a "_" character. Everything seems to have gone smoothly with the
exception of 1 thing that I've recently noticed. In the reverse DNS zone
there is a record containing reference to gc._msdcs.(domainname)
which refers to the IP of the server I transferred the GC role to
during the time I was rebuilding the original holder of the GC and all FSMO
roles. This server is no longer a GC and I was wondering if this may be
having an unseen effect on authentication. Also, I'm not even sure that
that record should exist in the reverse DNS zone?
Any help is greatly
appreciated.
