Are there any major limitation of the enterprise edition of microsoft xp enterprise vs professional. I am specifically talking about IIS for web applications and using crystal reporting. I set up a crystal report, delcared it globally and assigned it to open via a command button. When clicked, the report fails to activate. I have enterpise edition loaded on my pc (e-machines). I looked for the professional edition in the stores but there were no upgrade editions, only the full professional version.
