Yes - the file ssPaths_msplats.properties exists, and in it the variable SH_PATH is defined as c:/cygwin/bin/sh.exe

That file exists on mydbhost.mycompany.co.uk and is accessible by the user (I think) I am using to do all the SSH remote stuff (a user named cyg_server, who is in the Remote Desktop, Administrators, Users and ora_dba groups).

Is "remote logins" different from "remote desktop"? Because the error and the documentation doesn't make that very clear.
