The Problem
When Kantech EntrapassWeb is installed alongside exacqVision Webservice software running on 3rd party (COTS – Commercial Off-the-Shelf) hardware, there will be a conflict on port 80. Port 80 is the port responsible for receiving and responding to http web requests. Both exacqVision Webservice and EntrapassWeb have are configured to use this port as default.
- EntrapassWeb uses Microsofts IIS web server configured for port 80
- ExacqVision Webservice uses Apache web server configured for port 80

Who is affected
Anyone running Kantech EntrapassWeb and exacqVision Webservice on COTS hardware will be affected by this. Note that exacq-built machines that come with Kantech onboard have already been configured to eliminate this conflict. The IIS web service on an exacq-built machine is configured for port 81.
