LAN Connection flooded with packets to DC

Found some sort of trojan on 3 different computers that sends/receives packets constantly.  Did a netstat and it appears to look for the domain controllers and flood only those IPs with packets.  The traffic is not enough to bring down the entire network, but it is enough so the local user cannot access any websites or email in windows.  Did a ping test and it works fine to local servers and the internet.  I haven't been able to find any information as to which trojan this is.  The remedy that I have used up to know is to reinstall WinXP, but this takes time.  The odd thing is, which could be coincidence, is that on all 3 computers I recently installed the latest version of the AT&T Communication Manager (6.9.115)  The activity described above occurs a few days after installing the AT&T software.

I have run a full virus scan using Kaspersky and it didn't find anything.  Also ran Adaware which found nothing.  Hijack this didn't have anything that looked out of the ordinary.  I did find a trojan on a flash drive used by the user in a system.exe file.

Thanks in advance.

I've reset the Windows firewall and TCP/IP using Netsh command.  When I hook up to the LAN, immediately the LAN activity lights up and connects to my DC on these ports
IP Address : Port
TCP DC:microsoft-ds
TCP DC:epmap

In TCPView the process appears as System:4 and when I try to kill it, it does not die.

I removed the AT&T Communication Manager and 2 instances of Driver Installer in Ad/Remove programs.  Rebooted and it appears the problem as gone away.

Balman, you may also use the "netstat -an" command to manually check for rogue I/O activity.
