Weird DNS issue
Hello,
I normally do not post issues I face in my work place but I've been having this issue in my work environment and it's been increasingly annoying because I have not found a solution. To make this story short we recently changed one of our domain controllers to another physical box (the old one was getting...dated) and de-commissioned the old one. The cut-over worked perfectly except for one problem...some of our clients will not resolve the file and print server by its hostname...it will only resolve by it's IP address or in some cases by FQDN. At first I had thought it was our XP computers (all of them) that had the issue resolving by hostname but I was wrong when I figured out even some (not all) of our Windows 7 clients were experiencing the same problem. The only way to have clients that were experiencing this to have them access files or access the network printer was by IP address or FQDN of the server (even pinging). I have tried everything from the DNS/DHCP side of things on both the client's end and our DHCP/DNS server. None of our other servers are experiencing this. I just thought I would ask and see if anyone else has experienced this sort of thing and could get some suggestions
All servers mentioned in this post are running Windows Server 2003 R2 Enterprise
Here are the things I have tried over the past week:
1) Reboot the file/print server since promoting the new DC(DHCP/DNS server as well) (obviously the first thing I tried)
2) Re-registering the DNS entry for the file/print server
3) Added DNS suffix on client's end that were having this issue
Thanks for reading

You don't have Server 2008 DNS Servers right? So you couldn't use a GlobalNames zone?...
Deploying a GlobalNames Zone -
RomBUS Member Posts: 699 ■■■■□□□□□□Nope no WS2008 DNS.
Funny you mentioned GlobalNames...I enabled the WINS service because I had thought at first the Windows XP computers were relying on it. This helped us resolve by the FQDN when only the IP address was working at first.
Nothing changed from our file/print server TCP/IP settings if you want me to check there for the NetBIOS -
Asif Dasl Member Posts: 2,116 ■■■■■■■■□□Run through this article (it's a bit long!) but it might help to track down your problem... it definitely not DNS if you can get FQDN working.
Also, you're sure there is nothing in the LMHosts file of the XP computers pointing to the old server? You could deploy an addition to the LMHosts file by GPO I suppose.
Maybe you have 2 or more WINS master browsers and there is an election going on - just a possibility.
I'd check the NetBIOS advanced setting is at Default anyway. -
lsud00d Member Posts: 1,571Did you ipconfig/flushdns?
Are the workstations getting their settings via DHCP? If so, did you update the DNS servers in the scope options on the DHCP server?
Is the DNS registration a static A record? Or do you have the server set to register itself? It might be a stale record...
What happens via nslookup? What about 'ping -a x.x.x.x'?
What happens if you set a host file entry? -
RomBUS Member Posts: 699 ■■■■□□□□□□lsud00d,
I did perform a Ipconfig /flushdns on both client and the file/print server
I also removed the entry from DNS and performing a ipconfig /registerdns for a new entry.
All workstations are getting their DHCP scope options as they should be
Can't remember the result I got when I did nslookup. I will try the ping -a...I didn't think of that
Thanks for the tips
