I have an 800MHZ G4 Power book and a G4 350MHZ Power Mac both running OS 10.2.6. I've connected them using an Ethernet crossover cable. In my network windows on both computers I have chosen "built in Ethernet" Using DHCP and AppleTalk in on. In my sharing windows. File sharing is on. When I try to connect to server I get "Login Failed. Unknown user, incorrect password, or log on is disabled." Sometimes I am able to connect but only as a guest. I can never log on as as administrator. And only my laptop will connect using my desktop as a server. Things Ive tried: Bought a new cable. Created new users to try to connect. Repaired permissions in disc utility. Reset my password using my install disc. (I only use two passwords and have tried them both.) Tried every network configuration. DHCP, PPP, even manually entered TCIP address. This should be easy. Sorry this post is so long.
