We have a Windows 2003 R2 with a 12 GB OS partition. &nbsp;The only other software installed on this is backup software. &nbsp;We now have only 750Mb free on this drive. Adding up the sizes of all the folders on this drive only comes to about 8GB. Does anyone have any ideas what could be taking up the remaining space.<br />
Thanks

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
