Hello we have a SBS 2008 domain with windows XP clients. We have added some new Windows 7 clients to the domain with the requirement that users are able to RDP to their workstations. Currently RDP is not working to Windows 7 clients internally or externally even though it is enabled, when attempting to RDP internally to the Windows 7 workstation it prompts with an error that it could not connect to the computer. RDP to windows XP clients is working fine. Also if one of the Windows 7 clients is disjoined from the domain RDP access works, however once it is joined to the domain it stops working. I have tracked down the issue to two firewall rules that are set up to block RDP access, however these firewall rules cannot be deleted or changed as they state that they are created by the system administrator and cannot be edited. I have checked RSOP and there are no policies applied that affect the windows firewall aside from the policies that enable it. I also went through each policy in the domain and locally manually to ensure that nothing is applied that would block RDP Access. Any thoughts on where this firewall policy may be coming from would be greatly appreciated.
