after installation is complete, click on: Start, All Programs, Windows Resource Kit Tools, Command Shell 

Then enter the following commands. (Attention: they are case sensitive.) 

net user guest /active:yes 
ntrights +r SeNetworkLogonRight -u Guest

This policy needs to be set to remove the "Guest" account. 
Otherwise, you get an error:
