Barr Systems recommends that the Barr Enterprise Print Server (BEPS) run on Windows XP Professional, Windows 2000, or Windows 2003. In addition, BEPS can be used with VMWare. To use BEPS with VMWare, customers will need to use a USB virtual hub device such as USB@nywhere. This type of solution allows the BEPS security key to communicate with VMWare via IP. At the present time there are no known issues associated with running BEPS and VMWare. However, we are not VMWare experts. Consequently, we cannot provide the OS expertise with VMWare that we do on our regularly supported operating systems. We expect you to be the VMWare expert, but we would be glad to help.
