Right click on My Computer, choose Properties, then Hardware, then Click on the Device Manager button:
Attempt a hot sync and watch the device manager - it should "blip" and perhaps give you a Yellow Question mark in the other device area of the "tree".
Right click on the yellow question mark and see if your giving the option to install.
Then let me know if that does it.
If your getting a sound input of some kind on the pressing of the hotsync - then it would seem that the device is communicating through the USB port.
Also, I assume that you have Administrator rights on this computer at work?
Try the above and advise.
