Hmm .. this is where it gets even more interesting.  If I run:

$ ssh user AT W2003 date
Wed Jun 21 18:02:13 GMTDT 2006

.. then I get a result.  But other commands don't, e.g.

$ ssh user AT W2003 cat /etc/hosts
$ ssh user AT W2003 ls

Before running ssh-host-config I did:

- Right click My Computer, Properties > Advanced > Environment Variables
- Under System Variables, click New, add CYGWIN as the variable name,
add ntsec as the variable value
- Under System Variables, scroll down to Path, click Edit, add
;c:\cygwin\bin to the end of the string already in the field

Then opened Cygwin on the desktop, ran ssh-host-config and entered:

"Privilege Separation?" Yes
"Create local user SSHd?" Yes
"Install SSHd as a service?" Yes
"CYGWIN = " enter ntsec

Should I have done anything different there on W2003 ?

John
