"squishserver Failed to register with Windows firewall"

With enabled Windows firewall

When the Windows firewall is enabled the Squish IDE Runner/Server Log view might show an entry like this:

squishserver: Failed to register with Windows firewall

This should only occur on Windows Vista and higher, and when Squish is not being run with high/full administrator privileges (because the process is not allowed to register itself with the firewall then; possibly because of UAC).

This message is just for your notification, so that you do not forget to allow squishserver to access and bypass the firewall, or to add it to list of applications allowed to bypass the firewall yourself.

With disabled Windows firewall

When the Windows firewall is disabled the Squish IDE Runner/Server Log view might show entries like these:

CoCreateInstance failed: 0x800706d9
WindowsFirewallInitialize failed: 0x800706d9
squishserver: Failed to register with Windows firewall

These messages only report failure to handle or configure the Windows Firewall, and should not in themselves have any adverse affect on Squish or the squishserver.

However, if the Windows firewall has been disabled or shut down, this normally means that a third-party firewall has been installed in its place. A third-party firewall might affect the network-based communications of the Squish components (e.g., squishrunner and squishserver).
