Thanks, Jim,

We are not allowed to do anything with the registry, but I will ask the Tech 
who set up my home computer if he will do this.

I think this may do it.

How To: Transfer your PuTTY settings between computers frame end

PuTTY is tops on the short list of applications I install first on any
Windows machine. Over the years I've used PuTTY, I've installed it on a
huge number
of computers but I've always had one complaint; There isn't a configuration
file I can backup or move to a new machine.

Getting all the little comfort settings correct for each SSH connection can
be a pain. The third time you set emulation, keys, encryption type, etc.
each machine you regularly access, you lose patience. The fifth time you
find yourself re-entering settings you might do what I did, find a better
Moving PuTTy settings between computers is an easy task once you know
what's involved. We'll find the registry keys where PuTTy stores its
information and export them to a file. We'll then use that file we've made
to import our configuration on the target machine.

Exporting Your PuTTy Configuration

Putty stores its settings in the Windows registry. To save a backup of your
Putty settings, you'll need to export this registry key to a file.


(Simon Tatham is the original developer responsible for PuTTy)

1. Click Start->Run and type "RegEdt32" in the "Open" dialog. Click "Ok"

2. One RegEdt32 starts, you'll be presented with an application which looks
something like:

3. Press "Ctrl+F" to bring up the Find dialog. Enter the name of the key,
"SimonTratham" in the "Find What" field, and make sure only "Keys" is
in the "Look At" section of the dialog. Finally, click "Find Next"

4. The search may take a while, reminding us that the Windows Registry is a
large and mysterious place where dragons be. Let's use these few seconds to
reflect on the fact that you should never, ever, never change things in the
registry unless you are absolutely, positively, totally, completely, 100%
sure that you know exactly what you're doing. When the search completes
we'll see the key name for which we're looking.

5. Click File->Export. Give your file an appropriate name like, "putty.reg"
and click "Save"

6. We're done! Save the putty.reg file somewhere safe. The file doesn't
contain any passwords or actual SSH key values so, it's relatively safe
from prying
eyes. Still, it does contain your configuration and that kind of data is a
private matter.
Importing Your PuTTy Configuration

To import your saved PuTTy configuration on any other Windows computer
simply copy your exported registry key, right click on the file and click

Windows will ask you for confirmation that you want to import this set of
registry values. We know this file is safe, because we created it but, you
never import registry information from an unknown source.

That's all you need to know about moving your PuTTy configuration from one
machine to another. This can be really useful information when upgrading to
a new PC or, if you're an office IT guy where your users all have a
standard list of servers they need to connect via SSH, you can create a
reference configuration
on once machine and "share" it between every computer in the office.
