Well Jake, the monthly packages which you can see here
http://www.eukhost.com/monthly.php are offered on both Linux as well as Windows platforms and Windows packages do support Access databases and ASP. That's the reason I had mentioned in my earlier post that if you wish to order any of these packages, you will just need to mention 'Windows Package' in the 'Comments' column while signing up so we can setup your account on a Windows server with Access Database and ASP support.
The Windows Standard package you have pointed out is a Reseller Package and is also available on a monthly basis. Let me know if you have any further queries in this regard.
