You can check the Event Viewer on your server nslookup errors and also on the DC, should be easy to see what the problem is.
If you do an ipconfig /flushdns on your client pc, can you ping the file server afterwards? But yes you should definitely make another dc ratehr than 2003.
5(?) people looked into this and we had to guess a lot because the symptoms didn't make much sense. Event log on the server maybe, but who knows. Getting rid of SEP prior of anything else is his best bet IMHO.
Wait, something else coming to mind: You can't query the public google DNS (8.8.8.8) from your failing hosts?
you mean nslookup www.crayola.com 8.8.8.8? No
We need to investigate that. Are you sure that there's no firewall / Norton / Symantec / whatever installed on the print- or fileserver? Because that's not related to your DC.
What kind of internet connectivity do your failing hosts have? Directly outbound via a gateway? Some proxy?
That doesn't answer my question
Are you using some form of a proxy for outbound internet access? Like MS ISA/TMG, Squid, Astaro etc?No we are not
ok, so why the heck can't you query 8.8.8.8? This is almost a no-brainer.

I'm going to reboot my ESX02 host. I tried to do this from a few VM's and I see that none of them are working. Giving me an inkling into what could be the problem.
No one would know if any of these other servers are functioning. They are actually somewhat unimportant with the exception of the print and file server. I think it's the host.

That thing has probably been rebooted more in the past few hours than in months combined!

Why are they running if people don't need them?

I just mean non-crucial. They are needed it's just not anyone would notice if they were down. Everything on ESX01 is functioning. Could this possibly be an NTP issue with the second host? I know the VM's are supposed to sync with the host itself

Check the time, is it right? Then NTP isn't the issue.

Time does not affect DNS, though.

Probably not the source of the problem, but you shouldn't do this. Use NTP, have seen lots of problems with hypervisor time syncs.

No, they most certainly are not.

Just making it clear that the bit he was sure of, was backwards.

They asked me to troubleshoot our pendant system so I'm going to be gone for a bit.

Has this issue been resolved yet? Or are they pulling you to look at yet another problem?
Seems like you need some support, one person can't do everything..

you made my day... because in theory you are totally right, in reality, well, there are things called SMB and NGO etc.

So what is the current problem?
From the OP, he has a file server that can't see the 2003 DC.
He has a 2008 DC, has he tried changing the DNS settings on the file server to the 2008 DC?
Can he NSlookup from the 2008 DC to the 2003 DC?

I'm with Dustin. Who is overseeing the priorities here? I mean maybe that really is more important, but that seems unlikely. Who controls the prioritization of requests when they come in? What is your supervisor doing in all of this?

Hopefully planning for a new server AV solution...
