sspi or pserver authentication timeouts

Hello

I have installed CVSNT application on two windows 2000
PCs. On one PC the application acts as server and another PC its a
client.

Now the problem is the CVS client PC is trying to authenticate to CVS
server PC using sspi or pserver protocol but its getting timeout.

I am cvs client on win XP pc also they are getting authenticated with
win2000 cvs server PC.

I tried authenticating the same client PC to another cvs server PC
which is a windows XP machine, it works fine.

Problem seems to occur when both are Win 2000 PCs.

Windows 2000 version on both PCs is 5.0.0.2195 SP4.

Here is the error message:-

Logging in to :sspi:Administrator@gillespie-pc15:2401:/SHDSLInterop

Please see if anyone can help me with this problem.

thanks
