On our workstations, we have three DNS Suffix Search List entries when you do an IPCONFIG /ALL. The systems are not DHCP enabled, that have static IPs. Yet, there are no suffixes entered for the properties of the TCP/IP settings for the network connection. Nothing found in the registry either... So, where are these machines getting these suffixes from?
Also, we have a DC that when you do an nslookup by IP, it returns the wrong name. It doesn't match it's host name. We don't have reverse-lookup zones setup yet, but I presume this is a netbios name that was originally configured for the machine before it was dcpromo'd as a DC. How do we change it's netbios name... Again I could not find it in the registry of computer name settings.
I looked at all the group policies, and I could not find anything there. I even ran the rsop wizard... nothing.
I tried the debug command... New-dc-5 is not the hostname of the dc. So I don't get where it gets that from?
