What do you mean by the version of ASP??
ASP is a scripting language, using ADO connections to databases, so there are really two versions of things of importance, but no actual version of ASP.
These two version numbers of interest, are:
1. the version of IIS you are running on your server (or equivalent web server)
2. The version of ADO you are using (latest version = 2.5 I think, but don't quote me on that!!!)
