Hi,
I've been scouring the internet for a resolution to this problem and
have yet to find how this was solved. I've been working on this for a
week, and I'm not any closer to solving it. Thanks in advance for taking
your time to help solve my problem.
I have setup a password less ssh connection to a Windows 2003 Server
using the SYSTEM account with privilege separation.
Here is an output from ssh -v localhost:
