I'm having the same problem and it's really inconvenient. I'm not really sure that it's possible to solve it without giving full admin rights.
Running network scan as admin though a scheduled task doesn't work either.
Another option is to scan through TWAIN , buy you need a usb cable.
I've implemented the same solution for both the 3300MFP and the WC3220.
However, the users still "disappear" from the Network Scan Menu on the machine frequently. Have yet to resolve that issue (created a post here about it 5 weeks back).
Same problem in my company, I've managed to partialy solve an issue by using Microsoft Application Compatibility Toolkit and making Network Scan executable to always run as Administrator. You can find more info HERE
I wish someone from Xerox give us some proper solution because by using method above I must perform modification in every user mannualy, a bit cumbersome task :(
Thanks for the suggestion, however it appears Xerox Net Scan will only run for a standard user if UAC is off. It would be great if Xerox would correct this oversight in the future.
Sorry for my previous post. (something went wrong with IE9).
I was trying to post my thoughs about your problem and I think this might be solved via windows solutions.
I've installed the latest 3300mfp drivers for Windows 7 x86, and the Network Scan app won't run unless the user is in the local administrators group. As I understand it, users won't be able to scan unless Network Scan is running in the system tray.
Also, even though it is checked to run at startup, it fails to do so.
I have duplicated this issue on several computers. Any assistance would be appreciated.
