I have a major problem, that is I just got an e-mail from PC Connection and basically ISA will now coast me over $1400.00 When I started using the 120 day trial I knew it was around $800.00 and I budgeted for that amount. I?m just using ISA in my home with three computers one DC and two work stations. I have purchased two great books. One by Shinder and the other by Curt Simmons, I?m a correctional officer and trying to study networking so when I retire maybe I can find some extra income. I have NT4 back office then I upgraded to W2K and installed ISA. I guess my question is is there any way that I can make the upgrade version to work on my machine. The part number I got was E84-00212 for the upgrade and E84-00001 for the full version. ANY help would be appreciated.

It must be a part of BackOffice Server to qualify. Ok, we figured this out. If you have Backoffice, you can use upg adv as long as the proxy was part of Backoffice. If you have Proxy as a stand alone you cannot. This is from the most current product list. The last paragraph sums it up! Hope this helps you! Thank you!
