I found this one to be quite helpful as well as it mentions working with Unix-based DNS servers like the University does. It cleared up most of my issues with machines losing connections to the DCs. http://support.microsoft.com/kb/323417 Jon Galbreath MCSA/MCSE/Security+ Network/Systems Administrator International Studies and Programs Ph: 517-355-2350 [log in to unmask] -----Original Message----- From: MSU Network Administrators Group [mailto:[log in to unmask]] On Behalf Of Skutt, Tim Sent: Wednesday, November 07, 2007 3:30 PM To: [log in to unmask] Subject: Re: [MSUNAG] MS DNS on Win2003 server It's funny that you ask that, as we just gave the hostmaster our SRV records over here at business You give them the netlogon.dns file from your DNS server(s).

My Win2000 server is dying, so I'm migrating it to 2003R2. The old server has DNS installed, but it has never been quite right. Would like to get it right this time, unless there is some way to totally avoid MS DNS. Does anyone run their AD servers in 35.15.x.y address space, to eliminate traffic from outside of the building? (we've been behind a firewall blocking all MS-Net traffic for several years and really like the protection that provides from windows malware) thanks -John
