recently we upgraded to an active directory domain from a
workgroup. after changing I was recieving DNS errors>
afterward I contacted my ISP and they reassigned new DNS
primary and alternative. After changing the numbers I am
unable to view certain webpages. I can successfully ping
one of the DNS numbers and tacert works. The alternative
number does not ping or tracert. When I try to ping the
IP numbers that our domain resides on ping works but
tracert times out after leaving the garteway. The primary
DNS on the Active Directory is the IP of the server then
listed oare the other DNS numbers that were given to me
from our ISP. Our ISP claims that it is not an issue with
them.??
Any suggestions and/or comments are appreciated.

The issue is that your ISP advised you to put their DNS servers in your NIC
setup. Remove them from the NIC then put them in DNS as forwarders. You must
only use your local DNS on all AD domain members, even if you only have one
local. Just guessing you did not delete the root "." forward lookup zone in
your DNS so your local DNS won't resolve internet names. If you delete the
"." zone then you can use your ISP's DNS as forwarders.

The AD server should ONLY point to itself for DNS. Do not point the server to your ISP for DNS in the TCP/IP settings. In the
DNS MMC, configured forwarders on the DNS service to the ISP. That will solve both problems.

You can Change DNS servers on the fly. Just point it to itself.

So let me get this straight. TCP/IP settings, DNS should

only have the IP of the actual server. DNS forwarders
should list the ISP numbers. ALl this can be done during
work hours? Thanks, I am new to DNS.

Yes, it can. About the only thing that will cause the NIC to disconnect is
changing the configuration of the NIC itself, such as drivers and link type.
Point it to the IP of the local DNS server, even if it is the IP of the same
NIC on the server with DNS installed.
