Need some Help

[XxaxisxX]

OK so I have a computer that I want to set up a Garry's Mod server. The Computer is brand new with nothing but Windows XP on it. I followed this tutorial http://wiki.garrysmod.com/?title=Dedicated_Server_Setup#Windows Everything worked fine until I tried running the server with this batch file

Code:

c:\srcds\srcds.exe -console -game garrysmod -map gm_construct -maxplayers 16 -autoupdate

Then the error message pops up. It says "The procedure entry point ?Set@CThreadLocalBase@@QAEXPAX@Z could not be located in the dynamic link library tier0.dll." Then it says press OK. Then another error pops up saying "Failed to load the launcher DLL: The specified procedure could not be found." Any help on this matter would be greatly appreciated. Also another question, does the computer running the server have to have steam and Garry's Mod installed on it?
