We have dynamic DNS disabled. We ran into several cases were computers joined our domain and had the same workstation name as some of our servers, which caused all kinds of grief.

We ran into the same issue.  We ended putting a load balancer in front of our 
two DCs, which are also our private DNS servers, to solve this problem.  Now we 
can take down either DC with causing DNS problems with the XP workstations.

     That's the way it works in Vista/Win7. I'm not sure that's the way
     it works in XP. I think that XP is stupid - if it gets a response
     from a server, it uses that one server throughout an entire boot cycle.

     This is just a vague memory though. I've not supported XP in several
     years.

     Surely though if you have a pri and secondary DNS server, that after
     DNS1 times out on resolution then DNS2 will then be queried?

     +1 on that.  I think if the XP workstation had been rebooted, it
     would have been just fine.

     It's possible that XP may require a reboot before it retires an
     unreachable DNS server. I dunno. But it should work just fine.

     Sorry, long email.

     Windows 2003 Native Domain, two domain controllers, server1 and
     server2. Workstations are primarily XP, some Windows 7. Other
     servers (file server, email etc) are all Windows 2003. We have about
     150 workstations.

     We have AD DNS, and WINS. Server1 has FSMO roles Infrastructure
     Master, PDC Emulator, RID Master. Server2 has FSMO roles Domain
     Naming Master, Schema Master. Both are GC's.

     In the DHCP settings workstations get both server's IP's as DNS.
     Server2 is listed first, then server1. Primary WINS server is
     server1, secondary is Server2.

     Last night Server1 went down. It was off hours, but I got a call
     from some late night worker (using XP), saying they couldn't do
     anything. Couldn't reach any of the servers, or internet. I was able
     to get the server going again (bad memory chip, so I just took it out).

     I thought that if one server went down, the DNS/WINS look up would
     go to the other server. But it might be slower (note, I didn't try
     any of this, just going on what the user said). Comments?

     If I didn't get Server1 running again, what should I have done? I
     assume I should do the following.

     1. Seize the FSMO roles from server1, and put them on server2.

     2. Change DHCP so Primary WINS server is server2. Maybe even take
     out Server1 as DNS/WINS possibilities.

     Then work on getting Server1 running again, or replacing it.

     Did I miss anything?

     Thanks for any help and insight you can give.

     Mark
