The computer blocks incoming connections from a device

Possible cause

The Windows firewall on the computer that users connect their BlackBerry device to blocks communication from the device to the Enterprise Management Web Service.

Possible solution

Perform one of the following actions on users' computers:

• Create a firewall exception for incoming TCP traffic to RIMProxy.exe. The default port number for RIMProxy.exe is 5666.
• Create a firewall exception for incoming TCP traffic to the 169.254.x.x subnet.
• In the Windows Registry Editor, add the registry key HKEY_LOCAL_MACHINE\Software\Research In Motion\SCDeviceController, create a DWORD value that is named HttpProxyPort, and set the value to the port number that you want to use for incoming TCP traffic from a device.
