A special thanks to David Willard who provided the solution that worked!!

He said - I had a similar problem with another application. I solved it by
the number of colors on the PC screen, all the way down to 256.
You might want to give that a shot.

I did just that via the Windows menus & I was elated to see it work as

Thanks also to:

Terry Mitchell
Brion Leary

who sent other ideas to try!
What a Mail-List! You have come through again!!

Thank You!!!

The original message was as follows:
Sun Managers,

I am trying to get an xterm session established on a PC (pentium processor -
host name = "b2wkstn2") running Windows for Workgroups and Novell's LAN
Workplace ver. 5 from a Sun SPARC20 (host name = galaxy) running
SunOS 4.1.4 & X11R3. The LWP5 software provides the X-Window
functionality on the PC.

When I enter the command from galaxy (SPARC20)
xterm -display b2wkstn2:0
I get the following error message:

X Error of failed request: BadValue (integer parameter out of range for
   Major opcode of failed request: 91 (X_QueryColors)
   Value in failed request: 0x0
   Serial number of failed request: 22
   Current serial number in output stream: 22

I hooked up a sniffer to get the details of the X_QueryColors data packets
they are as follows:

1. galaxy -> b2wkstn2

Sniffer Summary screen:
     XWIN C Query Colors

Sniffer Details screen:
     XWIN: Request opcode = 91 ( Query Colors )
     XWIN: Colormap = 00000024
     XWIN: Pixel = 00000000
     XWIN: Pixel = 00000000

2. b2wkstn2 -> galaxy

Sniffer Summary screen:
     XWIN R Value Error Query Colors

Sniffer Details screen:
     XWIN: Error Code = 2 (Value)
     XWIN: Bad Value = 00000000

I'm new to the X Window protocol, but it looks like there is something wrong
or incompatible with the colormap on the PC & the Sun. I believe the PC is
using X11
version 11.0.4, Image = LSB, Bitmap = MSB, & it's from "AGE Logic, Inc.".

I can successfully xterm to another Sun and a DEC Alpha, but not the PC.

Can someone tell me what the problem is? Any help would be greatly
