NV7.1.3 , Solaris9, Fixpack2

Have anyone seen the following error?

"fatal IO error 131 (connection reset by peer) on X Server "server2" after 0 request (0 know processed) with 0 events remaining .....Couldn't open display"

Here is what we have done so far :

1- "xhost +"  on the Netview server

2- "xhost IP NetviewServer" on the dumb terminal of server2

3- ran "telnet NetviewServerIP" from a console on server2

4- ran "export DISPLAY=server2:0.0" on the telnet session to NetviewServer

5- ran "netview" on the console on server2 telneted to NetviewServer.

6- then I got the above error.

Q1: Help?
