I am working on a Windows Server 2003 GPO and have about 300 users using both IE 7 and 8. I have set the homepage for the users in the GPO, user config, windows settings, internet explorer maintenance, urls, important urls, and added the homepage to our intranet. This has worked fine. The issue is when users try to add other homepages on tabs. After a reboot and GPO takes affect and the only homepage is the one set in the GPO. The other homepages the user added on the tabs go away… I think it is because of we do not have Windows Server 2008? I do not see any info in GPO about Tabs? I have added the “inetres.adm” admin template.
