ssh is not an option for us. There is no ssh client built into Windows.
There are many important things that are not bundled with MS Windows. (I assume you mean the Microsoft OS by "Windows"). An ssh client is one of the more cruical things missing.
Fortunately the solution is quite easy. Just install and configure PuTTY on the hosts where admin access to any of your Filers is required -- you'll not regret it... To find where to download PuTTY, which is completely free, you can use Google -- a search engine just like MSN search (Microsoft) but much better.
