Problem with using Exceed

Hi Gurus

I am facing problem in using Exceed to connect to one HP Ux server. I used Exceed (XDMCP-Broadcast) but can't see the IP address of the server I want to connect to. What could be the reason for this ? (Network Connectivity is fine as I can connect using telnet)

Then I used Client Wizard (as given in this link also)
in the final step when I click Run with Display Host Replies checked, in the end, it gives:

Xlib: connection to "172.21.67.210:0.0" refused by server
Xlib: Client is not authorized to connect to Server
/usr/bin/X11/xterm Xt error: Can't open display: %s

Any ideas, where could be the problem ? Is something not running on the Server or there is a problem in a way I have configured Exceed ?

Thanks

Are both machines on the same subnet? Do both machines agree on the subnet mask and hence broadcast address?

Can you do XDMCP-Query?

Try doing XDMCP-direct to the host's IP address.
