SQL Server is a complex suite of software that has evolved dramatically over time. If you say "My SQL Server is doing X" it's highly likely someone is going to ask what version, edition and so forth you are using as different versions and editions support different features (or the features work a little differently) or there are certain hard-coded limitations from version to version or edition to edition.
To this end, I've posted a simple little script that will retrieve some very important information that is extremely useful to provide when requesting help. It does not require any permissions beyond the ability to connect to SQL Server and works on all versions and editions with the exception of the ProductUpdateLevel which only applies to SQL Server 2012 and above. You can simply remove this line if needed.
