Frodak, thanks for the message. Sorry for the slow reply, but I've been
out of town.
I was aware of all the information in the User's Guide. Using the
xhost commands as recommended actually caused problems with the
Xserver on Solaris. I tried the solution you recommended. I didn't
get any error messages, but as you mentioned it sometimes doesn't
work and that was my experience. So I'm still looking for a solution.

Subject: Using xauth with Cygwin-X
I use openSSH running under Cygwin-X to communicate with a
Solaris workstation at work. When I logged into Solaris with
SSH, I received messages that there was no valid xauth data
and that fake data would be used for X11 forwarding. My
mail reader (exmh) also complained repeatedly about failures
of xauth authentication.
I dug out my old X manual (which goes back to X11R5) and
looked up xauth. It suggested running this command under Solaris:
xauth -extract $DISPLAY | rsh my home PC with Cygwin xauth merge -
Since I didn't want to use rsh I did this:
1) (Solaris) xauth -extract $DISPLAY xauth.data
2) I transferred xauth.data to the root directory under
Cygwin, using SSH.
3) (Cygwin) xauth -merge /xauth.data
The last command told me that a new /home/larry/.Xauthority
file was created, which made sense to me. Otherwise there
were no messages.
I shut down my bash shell, closed my Cygwin X server, and
restarted everything. I still get the same errors when I log
into the Solaris workstation. Any suggestions?

Here is a link to the Cygwin/X user's guide on Displaying Remote Clients.
http://x.cygwin.com/docs/ug/using-remote-apps.html
In the past I was messing X11 forwarding with a Sun box and xauth was kind
of a pain to use with telnet.
In cygwin type
xauth generate your_host:0 . trusted timeout 300
xauth nextract - your_host:0
On the remote station:
xauth nmerge -
Select the output from the cygwin command and copy it to the input of the
remote station. Now the remote station can connect to the cygwin Xserver
for the next 5 minutes. Also resetting the Cygwin Xserver will invalidate
any keys generated.
The biggest pain is that it doesn't always seem to work. It seems
sometimes
that cygwin will always reject the key. Also, some programs will halt
with
this kind of failure when starting (e.g. dtterm):
X Error of failed request: BadAtom (invalid Atom parameter)
Major opcode of failed request: 18 (X_ChangeProperty)
Atom id in failed request: 0xda
Serial number of failed request: 1720
Current serial number in output stream: 1722
Others will crash while running, also with a BadAtom failure.
I didn't see these problems when using the xhost + method in the user's
guide.
YMMV
