My Main Desktop at home runs XP Pro SP 3. This has two very large hard drives that I keep all my information and products on along with the most recent Favorites which can no longer sync through windows live as they did before. My 3 laptops run Windows 7 Ultimate (two are Core 2's and one is an Intel i7) The smallest harddrive is 320 GB, one 500GB and the i7 is is 650GB. But I have tried many serveral ways to connect them and I know it must be something simple I am missing. I have read the Article ID: 969084 Description of the Remote Desktop Connection 7.0 and was about to just run with this option until I looked into the section:951608 (http://support.microsoft.com/kb/951608/ ) Description of the Credential Security Service Provider (CredSSP) in Windows XP Service Pack 3. From the PDF is sounds as if I would need to have a server X.509 certificate.So one of my questions would be is this true?Then my second question would be if I am not using a server is there a cost for the certificate?Thank you for any advice?Email removed for privacy1 person needs an answerI do too

You don't need to get a certificate to connect to XP Pro SP3 using Remote Desktop. I just verified that by connecting to my XP Pro SP3 computer from a Windows 7 Ultimate computer.To connect to your XP Pro computer over the Internet, you have to configure the computer's firewall and your broadband router to allow unsolicited Remote Desktop connections.Boulder Computer MavenMicrosoft Most Valuable Professional
