this is definitely a trojan of some kind...i have just come from helping
clean 2 w2kpro systems.

I should have written down the name of the files...but..go to
/winnt/system32/ and sort by date... you will notice there are several
programs that don't belong with very recent date/time ... i think one is
secedit.sdb or something like that...

another file is tftp<number> ...there are several of these files

there are also (i think) 3 files with 3 letters (with the same date and
time)... i think mdp or ndp or something like that.

also there is a fake taskmgr.exe ..it is called taskmngr.exe ...

norton dat dated 8/28 detected 12 virus (irc trojan) and was able to
quaranteen them.

i have managed to clean the systems but am having problems login in from one
machine to the other... it works in one machines, but not the other.... one
way authorization.

as i get more information, i will post...
