Russ,
Thanks for responding.
I've already checked with the ISP. They claim that I am using the right DNS
numbers and they haven't received any complaints from other customers.
There are two NICs in the server that are "teamed". Unless my customer
changed anything (which I seriously doubt), nothing on the server has changed
and this problem just started in the last couple of weeks. It has been
working just fine for months.
Using the IP address gets the same result from the clients (page not found).
Again, though...it works on the server.
They do have a box running Checkpoint firewall software, and this box is
controlled from their corporate home office and I have no authority over it
(which is fine by me, as it controls their VPN to the home office, also).
Downloads were slow a couple of weeks ago, but this seems to be doing better
lately (except for the sites that won't work, of course).
Thanks,
Scott
