Name that Trojan

[Nutcase_69 <nutcase_69 () e-mailanywhere com>]

We have an application server running NT 4.0.  We found the file serv.exe on
it and I know that this could be an indication of a Trojan.  We deleteed the
file and when we rebooted, the file re-appeared.  I trying to find out if
anybody know what Trojan might display this activity?  I thaught it was
freak but that seemed old and I didn''t think that it could regenerate the
.exe  Any Answers?

Cheers,
Eric
