Hi; i setup redhat 9.0 and I am running it under SBS 2000 network. Everything is ok; I can see the linux box on the network, I can reach every machine on the network from the linux box. Alse I can log on by typing sbs users username and pass on the linux box. But the problem is when I try to reach the linux box from any other xp pro boxes a window opens and wants me to typ username and password. There is user on linux and it has got a pass. I type it but the user name takes the domain prefix like domainName\usrName and I cannot reach the linux box. The security status of the linux is no firewall and every linux machine has f-secure antivirus and windows firewalls are off.. please help me. I am about to be mad.. :-(
