We're executing windows apps all the time but it requires some
"pre-work"

1st - You MUST fully understand the ins/outs of SSH

2nd - You MUST install SSH on each windows PC you work with. This is
the hardest part. It's only hard because you have to understand how
windows interacts with the SSH server.

3rd - Create an SSH key on your AIX server and copy your key from the
AIX server to the Windows server's key directory (this is usually based
on a user-by-user basis.)

4th - From the AIX server, execute an SSH session:

ssh windows_user@windows_ip "c:\path_to_office\excel.exe $file"

Good Luck,
