Thanks...

1.       It connects for a few seconds, displaying "SSH-1.99-Cisco-1.25".  I 
never get a login prompt.  Any keystroke (or doing nothing for about 5 seconds) 
results in "Connection to host lost.)

2.       More playing here has shown that it the situation is not consistent.  
I can connect to my NetApp storage appliances using PuTTY (on the same Win2008 
server), right after being denied access to the Cisco switch stack.

3.       The switch not allowing access from a Windows2008 server via SSH (but 
allowing it through Win7 and below) is a stack of Cisco Catalyst 3750 switches. 
 Current firmware is 12.2(55)SE1-IP-BASE-CRYPTO

4.       So far, have not found anything useful at the Cisco site about this.

5.       A possible clue...  using "telnet <address> 22" shows the SSH version 
of the remote system.  The Cisco, as mentioned, shows "SSH-1.99".  The NetApp 
and firewall systems all show "SSH-2.0".

Will the Windows client let you "telnet <ipaddress> 22" ?

Subject: SSH (PuTTY) session from Windows2008R2

Greetings!

We use PuTTY for SSH sessions to manage various devices.  An issue has recently 
been discovered by us here...

We have no problem logging in to our Cisco Catalyst 3750 switch stack via SSH 
from machines running Windows XP, Windows 7, or Windows 2003.  However, if we 
are logged into a Windows 2008R2 system...

Using PuTTY, we connect to the switch stack and get a login box.  After 
providing user name and password, we are denied access.

Using telnet (MS version enabled in the "Features" page of Control 
Panel/Applications), we can log in with no problem.

My preliminary Google searches seem to indicate that although SSH clients and 
servers are not a part of Windows 2008, it is supported.  So far, nothing 
regarding this inability to log in to other systems using SSH.  Again, this is 
weird as a telnet session from the same Windows 2008 machine gives access.

Anyone???  Thanks!!!
