My computer jojned DC win2003 server. Whenever I plugged in mu flash disk (USB), the windows display an icon on bottom right that found new hardware. But when I open windows explorer then could not found the removeable driver.

To open flash disk, I always have to access by 2 method:

- Right click on Start button and select explorer, then will see removeable driver on left panel
- Open Computer management, select Disk management, right click on removeable disk and select open

I tried remove USB driver but still the same.

If I login by local admin account then it is working normally. Dont need to access by 2 methods above

Anyone can help?

many thanks.

No, I tried change the driver letter but stills failed.
