VBScript: Find All Exchange Servers in Active Directory

The code but wanted to try to see if I could use my Recordset/ADsDSOObject skrills to shorten the code. The outcome isn't any shorter but it does get the version, so that's cool. Thanks, Sharfa, for pointing me towards the WMI Exchange_Server thing, too.
