My newly rebuilt Windows Server 2003 doesn't automatically assign drive letters to external usb devices.

I have to manually open the Disk Management Console and assign it a drive letter every time. It does this with two different drives in all USB ports.

I have been doing some reading and I don't have any network drives, I have also already tried USBDLM and it doesn't seem to have made any difference.

Specs: ProLiant ML150 G5 with Windows 2003 Enterprise and all updates installed.

Any ideas on what I can try to resolve this problem would be greatly appreciated.

You could have a look at which might shed some light, or perhaps to show EXACTLY what the puter is doing when you insert it. – Grizly Aug 26 '10 at 5:08

Open command prompt:

diskpart>automount          -tell us if automount is enabled
diskpart>automount enable   -enable automatic drive letter assignment if it is not on
diskpart>automount scrub    -remove old automatic drive letter assignments

reboot windows :)
