Intermitten DNS issues

[Norm]

I am getting intermitten DNS issues on three workstations
on the network. I have check the IP addresses and DNS
settings on all the workstations and everything is
configured correctly. The three workstations that I am
having intermitten DNS issues are XP Professional and one
Windows 2000 Professional workstation. All three are
current on Critical updates and Service Packs. They were
configured as DHCP, but since I am having issues I made
all three static with the DNS pointing back to both
internal DNS servers. I have forwarders on the DNS
servers pointing out the the ISP's DNS servers. Every
other machine on the network runs fine. These three
machines will suddenly display a web site not found
error, but you are still able to ping outside the network
and send email via exchange. I have flushed the dns
settings on the workstations. After about a minute the
web site works. I have also replaced the switch, but
that didn't help.

Any ideas?

Thanks

Do you get the correct IP using nslookup or netdig ? Check the local hosts
file also.

Yes I do get the correct internal DNS IP address via
netdiag.

I have ensured that the enable LMHost box is not checked
on the IP settings.
