XDMCP to Solaris Hangs on specific W2k systems, not all

[Patrick Jaromin <Patrick at JGSullivan dot com>]

I'm posting this to the newsgroup after what I believe was an exhaustive search
of the archives...my apologies if I've missed a previously posted solution.

I've got 3 W2k systems attempting to connect to a couple Solaris 8 boxes.
One system connected immediately, without any fuss using the basic:
XWin.exe -query <sun box> -from <w2k system>

When I attempt this with the other two, the program hangs shortly after
displaying the black screen and hourglass cursor. Only right-click-close
or task manager will kill the app.

After reading a few posts and the FAQ (on Sun's lack of 24-bit color depth 
support),
I noticed that the two that didn't work have video cards that only support 
8, 16 and 24 bit color depth
-- while the working system supported and was set to 32 bit.

Changing the other two systems to 16 or 8 bit didn't help....same hang.

Replacing the video card on one with an NVidia with 32-bit support didn't 
work either...same hang.

I also attempted the -fp parameter even though it didn't appear to be a 
font issue.

The logs I'm familiar with (through previous postings) don't seem to 
provide much information...and
look nearly identical in both the working and hanging case...with, of 
course the major exception that
the log stops after the hang while the working system logs additional info.


The XWin.log file looks like this: (with the -audit option)

and /var/dt/Xerrors looks the same (until the hang) for the working machine 
and the ones
that don't:

   Major opcode of failed request:  51 (X_SetFontPath)
   Serial number of failed request:  10
   Current serial number in output stream:  12

Is there anything else I can try? Did I miss something or are there other 
logs to check?

Thank you.
