Need some help please.

I have servers clustered using Centova, HOWEVER, when I try to login to remote servers via the main, I get Invalid Sign-On token.  I then can manually type the address to the server I tried to login to, and it will sign me in automatically.

Please advise as to where I may have done something wrong...I have redone all the permissions according to the instruction manual.

Please help as clients are not able to login to remote servers without directly typing the remote servers address either.

I know this probably doesn't help you, but I just tried to use remote logon and it works fine on all of our servers...

I can't see much that could really go wrong with this in all honesty?
