I installed Intel 15.5 software to team my SBS 2003 Nics and now DNS cannot be contacted

I installed prowin32 and teamed my nics on two servers in the domain. the first server is a Quickbooks server and teamed the nics perfectly. when I teamed the internal nics on my domain controller the domain servers became slow and for a time refused to boot normally. Now I disjoined one of my servers from the domain and when I try to rejoin it I ge a semaphore error. it apears DNS is working but not working at the same time. I cannot get exchange two work on the internal network but it works fine for our VPN users. this one has me stumped.

This is a DNS issue, you are correct:

There is a good guide for dual homed windows 2003 servers, compare it to your situation, because with the given information you have to work with guides and find the incorrect entry or provide much more information (2x ipconfig /all screens, Netdiag /test:DNS  => would be good idea anyway,...)

MS DNS or Bind?
I am assuming windows,
netstat -rn will dump your routing table where are your routes going to?
arp -an will give your arp info, what do you see in your arp cache?
if you have access to your swiitching hardware, do the NICs and MAC's associate correctly (nic1's mac is connected to nic2).

DNS if configured this way can bind to an IP or to an interface or to * whcih is any active interface with an valid IPv4 or IPv6 address.
What does your dns server state for ip-name and then what does your dhcp server say for ip-mac or ip-static. Are they all correct?
IF 192.168.0.3 is the DC and DNS serverr, is the dns server in the TCP IP properties 127.0.0.1 or to 192.168.0.3 or to something else (check both nics).
  If the the system states a locked fine, is it possible the system is trying to bind to both interfaces but is not configured to do so?

Before I go any further IS 192.168.0.3 your DC and DNS server (just want to be sure)

Also, just to be sure I'm no too far off base with this comment... :)

can you post results of NETDIAG (without switches) and DCDIAG please.

InterframeGap > SBS is a single server configuration with Windows DNS, it's also the DC and the DNS server.

we are coming closer..

NETDIAG without switches will provide all the IP configuration.
Oh cool, did not know that, now that I know I will down load that for my lab.... Cool...  Thanks.

The problem was with the server routes. After installing the Intel 15.5 software I teamed the NICs and for some unknown reason the server created a route to the local network through the default gateway. My default gateway is my Cisco 5510 ASA, when the router recieved the packets destin for the local network it dropped the packets. I raised the metric on the route to test and like magic everything started working. Here is how I did it
first at the commsnd prompt entered <route print> this showed the routes then did <route ?> this showed the route perameters, next ran the command <route change 192.168.x.x mask 255.255.255.0 192.168.x.1 metric 20> I did not use the IF command the scriot by default assigned the interface. Thanks to all for the excellent input.
