I just don't get it...why i do same thing on my computer (XP one) and
doesn't crash...if i go to other one (Windows 2003) crash right away...

Please any stuff i should install on the Windows 2003 computer...so it
doesn't make the program crash...just to keep runing normally as it does on
mines...

Here is some useful information...

szAppName : _3WorldLServer.exe szAppVer : 0.0.0.0 szModName : ntdll.dll
szModVer : 5.2.3790.1830 offset : 00001ad1

P.D: Notified of replies.

The program is a .exe file that works like a login server for a game. It
works all good, just that i am trying to run it with a patsh so doesn't allow
connections from outside of the server (anti-hack) in works while i test here
on my computer...but when i do it over there, and try to connect with a hack,
it does that...while here on my house says: FAILED, works on win xp but
doesn't on 2003 :s Just trying to avoid connections with a 3th party
program...that can cause big damage to server's database...
