I am having a nightmare with 2 options that are stopping me from completing my Windows 7 roll-out.
I can not get the proxy settings to set in I.E 9 no matter what I try, I have tried all the suggestions in the other threads and the closest I get to getting them in is using the registry setting, the exceptions all set, the proxy address sets but it does not set the tick in the box for "use a proxy server for your LAN2. If I use Internet Explorer Maintenance nothing gets put in for proxy, yet it applies all the other options such as links and favorites.
Settings injected using registry under preferences:
If I had any hair I would be pulling it out as it makes no sense!
My second part is deploying printers using preferences and Item level targeting, everything works fine here apart from "set as default printer". The policy puts the correct printers on the machine based on OU but does not set the printer I ticked to be default, it just defaults to Adobe PDF.
GP result shows no errors other than Event ID 1085 "Windows failed to apply Folder Redirection policy" which I do not understand as my folders are redirecting fine.
Have you tried GPP Internet Settings for setting the proxy in IE (this is what we use)? I would strongly recommend against using IEM - it's no longer supported on OSs with IE10 installed (it'll actually disappear from the GP console!) and doesn't apply the settings to the newer browser - not helpful if you upgrade soon.
As for printers - not sure sorry as we don't use ILT.
Which should already be part of your build? (and the two additional hotfixes listed in 2775511)
IE and GPP stuff has always been a bit funky. Once installed you should probably build a clean GPO on a patched machine and deploy that to your AD OUs rather than try to appply settings from an existing one that may be already be damaged from prior efforts.
If it's any help we use gpp for printers and it never seems to set defaults on first logon. It installs them but doesn't always set them defaults. A log off usually fixes this or wait for gp to refresh
It puts the proxy details I want in but does not tick the use a proxy for your LAN box, so I suppose the question is what would stop that box being ticked, I have used the GPP method and the registry method, both put the details in but none tick the all important use a proxy box.
