Theres a pc at work that wont allow usb pen drives to be accessed on a limited account, it asks for admin password.

Anyone know where the option is to allow them to use usb? Some computers are OK it's just one or two others.

I've tried allowing interactive users to use removable media but that didn't work.

OS is XP Pro

Cheers guys. Sad

Control Panel > Administrative Tools > Local Security Policy > Local
Policies > User Rights Assignment > Load and Unload Device Drivers and add the user to this group. Wink

you don't need a domain controller to change GPO's.

Start - Run - Gpedit.msc

Bunch of stuff in there for locking / unlocking features of windows.

looks like woosty nailed it though.

I had a good idea this was the place to set the permissions, but I didn't know which one allowed the USB to be used. smile

Don't you just need one PC to set up a local domain?


(It's been a while since I did this tbh (we were using Windows server 2003 at the time))

Technically yes. Practically no.

There's also the issue of licensing.

There is funding in September for a server. I'm gonna make damn sure I get the leetest rig possible.  tongue2

Have a look in the same area, Local Security Policy>Security Options

Loading and Unloading device drivers might still be regarded as an elevation to Admin Privileges so [User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode] might need to be changed to Prompt for Credentials instead of Prompt for Consent.  scratchhead

If it's working on most and not on some, then something has been changed, you could spend all your time looking for it or you could just blow the pc away, if i hit a snag on a pc that looks obscure and takes up more than an hour of my time i just re-image the pc.

I think the Admin Privileges to install a USB drive was implemented when people started to realise it could be a huge security risk.
Maybe some PC's have different security settings than others.. scratchhead
There's an executable on this page http://www.raymond.cc/blog/archives/2007/11/29/windows-requires-administrator-rights-to-install-usb-flash-drives/ which modifys the usbstor.inf file, which might work.
