Hi All,

I have a IE Plug-In(which is created using BHO-C#-VS2005-net2.0).It reads the user entered URLs and logs the details which urls are getting 404 error and redirected to specified link (mentioned in plug-in code)

I installed the plugin MSI in my machine(Admin machine) and i checked in IE 'Managed Add-ons',here i found my plug-in.

Then i checked its functionality,its working fine as expected.Its logging the 404 URLs and redirecting to specific URL mentioned in code.

Next, i insatlled the same MSI in other Machine(user machine-Same Configuration) and i checked in IE 'Managed Add-ons',here i found my plug-in.

but my plug-in is not working in this machine.Then i checked the all the settings finally i found one thing

in my machine Protected Mode is OFF and in user machine Protected Mode is ON.

And user machine IE contains some URLs in IE options-->Security-->Trusted Sites.

For those Sites my plug-in working as expected.But user machine dont have access to edit/upadte the URLS.

Then i checked in my machine(admin machine) with Protected Mode ON and I added some URLs in Trusted sites,My plug-in is working metioned URLs in Trusrted sites.

So, if i should maintain the user URLs list in my code then how can i override the issue with Protected Mode is ON.

OR is there any probelm with setting in deployment MSI or else?

Finally can any one suggest me for 'how can i program that plug-in will work in Protected mode on/off states for all URLs?'

Thanks In advance.........
