LCS has multiple Network Adapters

Problem: LanSchool Connection Server has multiple network adapters.

Cause: If you install the LanSchool Connection Server on a machine/VM that uses multiple network adapters, and each adapter has a different subnet, then you will  have to tell the LCS software on what network adapter to communicate on.

  • Access to the LanSchool Connection Server
  • Access and knowledge of Windows Registry

Navigate to the registry setting for LanSchool Connection Server HKLM\Software\LanSchool, you will have to create two entries in this location:

Both entries are REG_SZ

IPSubnet (value equals their host IP address e.g -
IPSubnetMask (value equals their IP subnet mask e.g -

Restart the machine to use the new registry setting(s).
