Loose communication to all devices after upgrade to PME 8.x

Issue
The Siteserver will periodically shutdown after upgrading from SPM 7.0.1 to PME 8.x.
This causes the software to stop communicating to all devices and gives the appearance of complete comm loss throughout the system.
Restarting the Siteserver will restore communication but only temporarily.

ION SystemLog may also be filled with translator errors related to all custom modbus device types that functioned without issue on the previous version.

Cause
In our efforts to make the software more secure it caused an interference with IPv6 adapters being enabled on the server.  These adapters attempt to make the connections and bridge between IPv4 and IPv6 at intervals and cause the software to view the connections amongst the different software components as a threat to the system since the IPv6 protocol appears to be from a different machine.

Resolution
Disable all IPv6 properties in LAN adapters.  This will require confirmation from your network department that this protocol is not being used for any of your other utilities on this server.
1.) Open LAN adapter properties in the Network and Sharing Center.
      a.) Go to Start> Control Panel
      b.) Click on Network and Sharing Center
      c.) On the left select Change adapter settings
      d.) Right click all adapters one at a time and select properties
      e.) Insure that Internet Protocol Version 6 (TCP/IPv6) is deselected for all adapters.
           

2.) Disable adapters that are not visible in the Network and Sharing Center
      a.) Open a command prompt window
      b.) Type ipconfig
      c.) Note the listings of adapters available.
      d.) Anything listed as ISATAP, TEREDO, or 6to4 must be disabled.  Disconnected is not sufficient.
           
      e.) To disable each adapter type the following lines individually and press enter.  You should receive an OK if completed correctly.
            netsh int ipv6 isatap set state disabled
            netsh int ipv6 6to4 set state disabled
            netsh interface teredo set state disabled
            

This should disable IPv6 on the host device and stop the IPv6 stacks from interfering with communication of the software.



~~Notes:
ISATAP (Intra-Site Automatic Tunnel Addressing Protocol) is an IPv6 transition mechanism meant to transmit IPv6 packets between dual-stack nodes on top of an IPv4 network.
In computer networking, Teredo is a transition technology that gives full IPv6 connectivity for IPv6-capable hosts that are on the IPv4 internet but have no native connection to an IPv6 network.
