Well I have an issue that is a little odd. One of my users can login to any other machine on our Windows 2003 Domain and plug in a USB jump drive, and it installs fine, but when he goes back to his own PC, (once again with only Standard User Privileges) and he cannot install the USB Jump Drives without Admin Privileges. I have installed the USB drives on his PC with my Admin Login and then it will recognize the USB drive that I installed with Admin rights under his user login. So then I grab another USB drive fresh out of the package (exact same type A San Disk Cruzer) and once again the new USB drive will not install without Admin Rights. This is only happening on this one machine. I have SP3 and all updates installed via WSUS. I know that this is not a Group Policy issue as he can install on other machines with his user login without issue (and he is a standard user where ever he goes) but if I give him local Admin Rights to his machine it installs fine. I also tried a couple of other models of USB drives and get the same issue.
