Cisco :: 3750 / Unable To SSH To Switches

We are running CISCOWorks 4.0 (LMS).I can connect to and update the majority of my 3750's but I have about 20 that result in failure when attempting to update the image on those devices.The return error is "SWIM50001: Cannot connect to the device "IPAddress" using SSH and TELNET."  When running "sho ssh" you see connection for the current ssh tectia login but nothing pointing to the ciscoworks device.When I run "sho ssh" from a different device I see both connections, 1 from my desktop ssh connection and the other showing username of ciscoworks.I ran the Discovery tool, again, but no joy.I was looking for a manual way to add that connection but again nothing. How to make the ssh connection between ciscoworks and the edge device?As I said I can ssh from my desktop and manage the box that way but ciscoworks simply won't allow it.
