Hi,

a UT2004Demo server Ban only the GUID of a user or? Is it possible to change the GUID in the Demo? Because the Demo does not have an cd-key like the retail version...

And sorry for my Bad English! 

Try change the ip, computer name, and if necessary mac hash.

IP change was the first what i tried. And i changed the Computername and faked my Mac-Adress But still the same GUID...

Player GUID is based on CDKey. CDKeys for retail version of the game are unique, but everyone who uses the UT2004 Demo has the same GUID as the CDKeys are all the same
