NetMeeting Error

I am using WinXP Pro with all MS updates. When activating Netmeeting (start-run-conf)I receive the error message “windows cannot find ‘conf'”. I have compaired my PC to another identical PC and the files in the netmeeting folder are the same. When I try to run netmeeting from the netmeeting folder I see the netmeeting splash and then it quits. The first time however I am prompted to input my user information, after that I only see the netmeeting splash. The task manager will show conf.exe open and then close. I have tried disabling the XP firewall with the same results. Has anyone else experienced this problem?
