DS ControlPoint fails to connect to DigitalSENTRY video system.


Note: Clients operating on earlier versions of DS software will not function properly when connecting to a server running DS 7.13.84, update DS ControlPoint to v7.13 or later.

Verify everything:

  • error message during connection:
  • server software version:
  • client software version:
  • server hostname:
  • client hostname:
  • server IP address:
  • client IP address:
  • network topology: LAN/WAN/remote site via NAT/VPN
  • network cabling: UTP/Fiber/Wireless/Ethernet over Coax
    • After cables (copper or fiber optic) have been installed, have them certified

Troubleshooting steps:
Network verification:

  • ping server from client
  • ping server hostname from client
  • ping client gateway address from client PC
  • ping server gateway address from server
  • ping client gateway address from server
  • ping server gateway address from client
  • Click here to go to a Microsoft Technet article on how to ping.

Client configuration verification:

  • correct hostname or IP address
  • correct system type
  • correct username and password


Advanced troubleshooting steps to be performed in conjunction with the local IT department:

  • Antivirus software
    • Temporarily disable antivirus software on the client PC and server (if used)
    • If the connection is successful, start the antivirus software back up and configure it to allow DS ControlPoint to run
  • Local firewalls
    • Same as Antivirus step above
  • Port forwarding rules within NAT router
    • Verify the SQL Server, SQL Server Browser, and DS Video Server service are configured correctly
    • Visit portforward.com for more information
  • Port filtering within routers in the network
    • Same as NAT router step above
  • Network firewalls between internal/external networks
    • Same steps as Local Firewall and NAT router steps above
  • Network packet analysis (Wireshark or other packet capture utility)
