Cannot RDP into Windows 7 PC on SBS 2003 network

Hi Experts,

I have a Windows 7 PC running on a SBS 2003 network.    It is the first machine with Windows 7 which I have added to SBS 2003.   All seemed to be working okay until we tried to connect remotely to the desktop through the Remote Web Workplace.   I assumed something in the firewall was blocking the connection so I went to check and found 2 red crosses over the remote desktop inbound connection.   The problem is that the system won't allow me to alter either rule.   it seems to think that there is a group policy in place which is overriding the local settings. RDP errror
However, I have been through the Group Policy in detail and cannot find anywhere where I might be blocking this and RDP via Remote Web Workplace is working fine for all the Windows XP Pro machines.

Thnaks in advance
Jon

Windows 7 has two methods of modifying the firewall settings, the basic one through control panel and advanced through mmc.

open gpedit.msc on the windows 7 PC and see if you can modify the setting there

thanks dpreston - i'm not hugely familiar with the workings of group policy so could you point me exactly (or even roughly) where to look?

Expand Administrative Templates, Network, Network Connections, then Windows Firewall

From there you should be able to find it, i am not near a windows 7 pc at the moment so can't be more specific. When i get to one if you haven' t found it i will post again.

doreston68 is correct in the path to the Firewall GP setting for RDP. Under Windows Firewall, there are two profiles (Domain and Standard). Under there, the setting is "Windows Firewall: Allow Inbound Remote Desktop exceptions. But you have to specify what IPs can access this PC when you enable this setting.

Boilermaker is also correct but you can enter * to allow RDP connections from any IP

Have you managed to change the setting?

Hi - Yes I have managed to change the setting both in the domain and standard profile but I still can't connect via remote desktop (either through the remote web workplace or using another PC on the LAN).   It's bizarre because when I take a look at the advanced firewall settings there are 4 remote desktop settings - and both the inbound connections are enabled.  there is also no other form of firewall on the machine and I can accept incoming remote desktop connections through the router

Remote Web Workplace uses TCP port 4125 for its remote desktop feature, you need to open this port on your firewall

Looking at your screen print, it appears that there are 2 manually created Block Rules for Domain and Private networks on port 3389 (RDP). Immediately following these block rules are the built in Remote desktop rules again for Domain and Private, allowing ANY for inbound port 3389.But rules are processed in order and the Block Rules are probably geting met first.
