[cvsnt] Im not able to login from a remote PC

[pavan kumar]

Hi ,
   Im new to CVSNT, I have installed cvsnt-2.5.03.2260 on one system.I have
installed wincvs on other system which the systems are interconnected.
   Im able to login and Checkout the CVSRepository on the CVSSERVER(using
:pserver,:sserver protocols).
   Here the problem is I m not able to login from a different remote system.
   It is giving that

cvs [login aborted]: connect to ComputerName:2401 failed: A connection
attempt failed because the connected party did not properly respond after a
period of time, or established connection failed because connected host has
failed to respond.

Please suggest me a solution for this

Thanks
