Configure the Firewall to allow DCOM connections to O&K Print Watch.

As part of that default configuration, DCOM connections to a Windows 2008 (and higher) server are blocked. However, there are various scenarios where it would be advantageous to allow DCOM connections to that print-server (for instance for Control Program or O&K Print Watch Service).

• 1On the print server, open the ‘Windows Firewall’ application from the Control Panel.
• 2Click ‘Advanced Settings’ link in the left-hand pane.
• 3Right-click on the ‘Inbound Rules’ node in the tree view and select ‘New Rule…’ from the context menu.
• 4The ‘New Inbound Rule Wizard’ will open. On the ‘Rule Type’ step, select ‘Custom’ and click the ‘Next’ button.
• 5On the ‘Program’ step, select ‘All Programs’ and click ‘Next’.
• 6On the ‘Protocol and Ports’ step, in the ‘Protocol Type’ dropdown menu select ‘TCP’.
• 7In the ‘Local Port’ dropdown menu select ‘RPC Dynamic Ports’.
• 8In the ‘Remote Port’ dropdown menu select ‘Specific Ports’, and enter ’1024-65535′ in the box beneath.
• 9Click the Next button.
• 10On the ‘Scope’ page, under ‘Which local IP addresses does this rule apply to?’ select ‘Any IP Address’.
• 11Under ‘Which remote IP addresses does this rule apply to?’ select ‘Any IP Address’ to allow all remote connections, or select ‘These IP addresses’ to enter the specific IP address(es). Click ‘Next’.
• 12On the ‘Action’ page, select ‘Allow the connection’ and click the ‘Next’ button.
• 13On the ‘Profile’ page, select only the ‘Domain’ option and click the ‘Next’ button.
• 14On the ‘Name’ page, name your rule suitably (e.g. O&K Print Watch incoming DCOM connections) and click the ‘Finish’ button.
• 15If the rule shows as disabled, enable it.
