problem login with WINCVS

[JM Murillo]

when i try to do a login with Admin->login option in wincvs, the console
indicate this:

******************************************************************
CVSROOT: address@hidden:/var/cvs (password authentication)

TCL is available, shell is enabled : help (select and press enter)

NEW CVSROOT: address@hidden:/var/cvs (password authentication)

cvs login

Logging in to :pserver:address@hidden:2401/var/cvs

Unknown host 192.68.0.120.

*****CVS exited normally with code 1*****
********************************************************************

what's the problem? i have windows nt, and with another machines with
windows nt and another user it don't indicates any problem.
why puts a "." following the cvs server ip address?

Thanks.
