Users cannot get to certain websites, but my servers can.

Has anyone seen this before??? My pc, which is in the domain cannot
get to a particular website. However, if I remote into my servers and
try it, i can from that location...Any ideas???

Does your network run a proxy server. If so the servers may not be going thru the proxy and the workstation may. If that is the case your proxy has certain websits restricted. In internet options change your setting so you dont go thru the proxy.

We don't run any type of proxy servers or ISA. Its a straight shot to
the internet. We go through the same internet pipe which is wierd on
how some of my servers can get to the website and I can't on my own
PC.

DNS problems? Presuming you're using AD, do all clients and servers point
only to the AD-integrated DNS server in their IP configuration, and you've
set you DNS forwarders on the DNS server itself, that point to your ISP's
DNS servers?

You may want to check out your hosts file(s) and see if
they are plugging the way also.

For the ENTIRE organization?? Hardly the answer...

This is happening on my current pc as well and I have nothing in my
host file

Like Lanwench says. Where do your clients point to for DNS? They
should *only* point to the internal DNS servers. Where do your servers
point to for DNS? It should be themselves. Are the DNS servers set to
either use root hints or forward requests to an outside DNS?

The clients should NOT be configured with internal DNS first and
external DNS second. Anything else leads to problems.

Yes.. I have 4 IP fwds in DNS that point to my ISP's Internal DNS
Servers...

DHCP assigns all my clients their IP/DNS numbers. The dns numbers are
pointing to internal IP Address.. Here is the kicker.., WHY can't my
clients get to the websites but my Servers CAN ????

1) Do a DNS lookup (nslookup) for an internal machine, eg the DC.

2) Do a DNS lookup for say www.microsoft.com.

You said, I think, that you don't use "hosts" files so if the above
fail, it is a DNS problem.

3) ping and tracert to a local address, ie the DC.

4) ping and tracert to any external IP.

If either of the above fail its a routing problem, most likely.

5) Try to access a site. What is the exact error message?

(You may have done all this already of course).

Cheers,

And nobody is specifying anything other than your internal DNS server IP in
their IP config?
