FS231 Network Service Configuration Error, the Universal Driver, and the Windows Firewall

As Microsoft's operating systems become more secure the communication between OpenInsight and the Universal Driver can be blocked by the Windows Firewall causing a FS231 Network Service Configuration Error.


Typical Universal Driver 4.7 and Universal Driver 4.7 NUL installs utilize TCP port 777 for communication between OpenInsight and the Linear Hash service as specified in the REVPARAM file.


We recommend creating an Inbound Rule to allow port 777.  If your firewall is managed by Symantec or some other anti-virus software then the inbound rule will need to be put in place with via that software.

Below please find the steps to create an inbound rule to allow port 777 on the Windows Firewall.
