We have a windows domain and I'm having issues opening .ppt files from a website. They will only open in Internet Explorer and not Powerpoint. I have looked at some sites with suggested registry edits but have not been able to get them to work. I have many computers that need to be able to access the ppt files with powerpoint and am hoping there is something that can be pushed out in group policy to disable internet explorer from opening office docs. The PCs are running Windows XP Pro with Office 2003 Standard. It's a Server 2008 domain. All users that will be logging into these PCs are power users. If anyone has any ideas, I would greatly appreciate it. Thanks.
