I bought a copy of ISA that comes with the small business server. I have already installed windows 200o server and Exchange. I also have the IIS running but when i tied to isntall ISA, it asked for a 10 didgit key. The only key I have is the key that comes with SBS and it isn't 10 digit and neither does it work. Has anyone faced this problem before? Titus Syengo.
