I could be wrong just a guess, rename your computer. From what I have seen it displays "UserName on ServerName" in the browser list. Changing the name of your computer should change the "ServerName".

That "pc name" problem is also in OFP/RES...... if you don't have the resistance.cfg set up properly. So surely it's possibly in the server.cfg (I believe thats what it's named from other post).
Maybe this will help you Parameters (http://community.bistudio.com/wiki/Category:Armed_Assault:_Startup_Parameters)
