GUID ping (Q249256)

[Mykhaylo Khodorev]

In Q249256 I saw an interesting thing. They wrote server should be
pinging by their GUID. I tried such thing on three systems, but they didn't.
Did I miss anything? Can it cause any problems?

The article is referring to pinging the GUID record that a domain
controller registers in DNS. It is by these records that other machines
locate domain controllers. What you should actually being trying to ping is
<GUID>._msdcs.<domain>.<com>.

First, every DC shouls only be pointing to an internal DNS server. On the
DNS server they are pointing to you will find under the Forward Lookup zone
a _MSDCS folder. In that folder should be the GUID record for every DC in
the domain. If the records are not there, verify they are pointing to this
DNS server and not pointing to an external ISP DNS. Then, stop and start
the netlogon service. This will cause the DC to register its record on the
DNS.
