I think that I am encountering the same problem. I also have troubles with
a Windows 2000 client trying to connect to a Linux server (in my case the
server is using Debian 2.2 rather than RedHat).
As an example I ran "omniNames" in Linux and "nameclt" in Win2k.
I used the following command line flags..
on Linux (hostname heater):
/usr/local/bin/omniNames -start -logdir /var/local/omni -errlog
/var/local/omni/omniNames.errlog -ORBtraceLevel 20 -ORBtraceInvocations
on Win2k:
nameclt list -ORBInitRef NameService=corbaname::heater -ORBtraceLevel
20 -ORBtraceInvocations
The output from these commands are attached to this email.
Note that that other combinations of client & server OS work fine, ie:
Win2k-omniNames Linux-omniNames
Win2k-nameclt ok fails
Linux-nameclt ok ok
Regards,
Luke.

That error is "Connection reset by peer", which suggests that the
Windows end closed the connection for some reason. What trace do you
get on the Windows end?
Cheers,
Duncan.
