First of all might I suggest you use windows explorer to zip and unzip files - but that's another topic.

It might be something to do with the permissions your website is running under. In IIS, a web site will usually run under the IIS_ASPNET account (or something like that). The problem is this account has very limited permissions. What you probably need to do impersonate a user who has sufficient authorities to not only run but create the file. Just google asp.net impersonation and you should be fine.
