What does "can't login" mean?

Do you get "Login incorrect", or do you type in the password and it
hangs, or do you get messages or what?

Is NIS the only dependency that the other box runs? It doesn't serve
NFS to this machine does it?

When i put root and the password it hangs wainting , i do not get
messages only it hangs.The machine do not serve NFS for the clients
only NIS..

Another cause could be something [that probably shouldn't be
there] that causes an nfs mount and the particular server isn't
responding. The worst instance I can remember of this was
on an NIS server where the maps had been placed on network
storage and the NFS server with the maps physically resident
was a client of that same NIS server. It all worked when
migrated until the power went out and all servers had to
be rebooted.

My assumption is that technically the login succeeds, but something
spawned by the login is hanging.

If possible, I'd log into the box, open a window, and do a 'exec login'.
In another window, run a truss on the login process. Then, pull the
cable or otherwise make the NIS server unavailable. Now login as root
in that other window.

You might want to do that twice: once with, and once without NIS
present. See if the truss shows anything interesting being spawned
which hangs.

quota is often a problem, but this one doesn't sound like it.
