Trying to troubleshoot a problem with a user's USB key, can reproduce across multiple Windows 2000 and Windows XP machines. With USB key inserted, the local PC's OS detects the key as a local drive. I create a connection to a published Windows desktop; when logging in with Citrix Server Administrator rights the USB and physical PC hard drives are detected as client drives. When logging in with Domain User rights only the physical PC hard drives are detected as client drives - No USB key mapping occurs. Why doesn't the USB key show up as a client drive? Suggestions on things to look at pls? Thanks!
