GPO not working for IE9 proxy settings
Some background: Domain controllers are a mix of 2008 R2 and 2008, clients are Windows 7 Enterprise x32 /w SP1 and IE9. I'm having an incredible issue right now with proxy settings applying intermittently on student workstations. The proxy GPO was set using User Configuration>Windows Settings>Internet Explorer Maintenance>Connection/Proxy Settings. What will happen is out of a cart of 30 or so netbooks, 2/3rds of the students will fail to pull proxy settings. Looking at one of the afflicted machines shows the check box in IE not checked, and the proxy address field blank. If you run RSOP it shows that all the policies have successfully applied without error (no filtering, etc), and if you drill down back through User Configuration>Windows Settings>Internet Explorer Maintenance>Connection/Proxy Settings it's clearly there. IE is simply ignoring it, and with the randomness I don't know what to make of it. Has anyone else come across this issue?
