Windows 2003 Server RC2 SP2

3COM 3C940 GB Onboard NIC

 

I recently installed 2003 server. Got the latest updates. I then set up this

machine as a domain controller on a new forest and followed the the

instructions to set up the DNS. Now if I try to do anything over the

interent, I am lucky to get a full page to load. There seems to be all kinds

of communications problems. If I stop the DNS and point everything over to

my old server which I want to decomission when this one is up and running,

all network performance is perfectly fine.

 

Any thoughts?

Re: Network Performance Drops to a Crawl after Installing DNS

 

Hello Howard Swope" howard_swopeAThms3DOTcom,

 

Is it really a Release candidat version? Otherwise post an ipconfig /all

from the machine.

 

Best regards

Re: Network Performance Drops to a Crawl after Installing DNS

 

Hello Howard Swope" howard_swopeAThms3DOTcom,

 

Did you configure a forwarder to your ISP's DNS on the DNS server properties

in the management console?

 

Best regards

Re: Network Performance Drops to a Crawl after Installing DNS

 

Some more information:

 

My DNS setup looks slightly different then that of another functional domain

(separate forest). The current one has an _msdcs.xxx.xxx entry under forward

lookup zones and it has no reverse lookup zones defined. My other dns also a

pdc on 2003 server doesn't have this entry and it does have a reverse lookup

zone defined. I am not sure if this has any effect on anything.

 

I am also getting some interesting information in the dns event viewer:

The DNS server encountered an invalid domain name in a packet from

68.87.66.196. The packet will be rejected. The event data contains the DNS

packet.

 

I am getting a few of these errors. This address is one of the DNS servers

which I forward to. I would think this might be indicative of some type of

nic / driver issue. However, when not configured as a DNS the networking

flies.

Double check some of the info regarding SP2 in this KB:

http://support.microsoft.com/kb/945977

 

Also be aware of http://support.microsoft.com/kb/945466

and http://support.microsoft.com/kb/947775

 

Make sure your NIC drive is the latest as well. This now seems to be a

requirement of any SP2 install.

Re: Network Performance Drops to a Crawl after Installing DNS

 

This is the only DC in your new forest, then? Old server and new server

are in different forests? Are you using the same forwarders that you are

using on your old server in the DNS properties in the "Forwarders" tab of

your new server? Have you tried clearing the cache and restarting DNS and

then going into CMD and running an "ipconfig /flushdns" and an "ipconfig

/registerdns"? From CMD, can you ping a website, for example, http://www.google.com,

or maybe trying ping google's IP (64.223.167.99)? Can it ping both, or just

the IP address of the website? Or neither?

I cannot test your forwarder, it refuses queries from me, probably an ISP

restriction in place, try changing the forwarder to 4.2.2.2 or 4.2.2.1 both

are very fast and reliable.

Re: Network Performance Drops to a Crawl after Installing DNS

 

That seems to be the problem. I switched over to forwarding to the DNS

enteries that you mentioned and everything is happy. I don't understand why

this is a problem. My other DNS server in the old forest is forwarding

requests to these same DNS servers without issue. I think these are the DNS

Servers the Verizon FIOS provides for their customers use. I forget as I set

it up a while ago.

 

Any thoughts as to what would cause one server to have difficulties and the

other not?

 

Who runs the servers at the addresses you provided?

 

Thanks

Probably the same reason I cannot get it to resolve names, it set up to

accept queries from only certain networks.

Verizon owns the IP addresses and the domain in the PTR, so I'm pretty sure

Verizon operates them.
