In most Windows applications, the version number is listed under Help > About. For some reason, IIS Manager is an exception. There are significant differnces between versions of IIS, so it’s crucial to know which one is on the server.

Look for it in the right pane of IIS Manager, under the Version column. The column may be obscured if you keep the window rather small, as I usually do.


This seems like such a simple thing, but it can be quite annoying. Perhaps they’ll make it more consistent with user expectations in a later version of IIS.
