Exacq Support has identified an issue preventing fail-back due to VFBA.exe being blocked; which uses port 28774.
Windows Versions
It is recommended to create both inbound and outbound Windows firewall rules on the SPARE server to allow communications through port 28774 for the Windows Firewall.
** Due to issues with the Window OS, disabling Windows Firewall does not allow this thru, and the creation of the FIREWALL rule is required. **
On a Windows Machine, do a search for FIREWALL and click on the option for Windows Firewall with Advanced Security.
Click on the inbound/outbound rules and select NEW RULE from the right.
Highlight Port and click NEXT
Select Port 28774 and click next.
Be sure to repeat this for BOTH Inbound and Outbound connections.
In some cases it may be necessary to “whitelist” ExacqVision components (core.exe, edvrclient.exe, including .ps and .psi file types, and ExacqVision Enterprise System Manager components) Enterprise Manager, Server and Client software along with vfba.exe within any used Antivirus configuration.
