Network name cannot be found when remediating a client machine with GFI LanGuard

Author: Luis Fernandes

Answer

Problem

Network name cannot be found when remediating a client machine with GFI LanGuard.

Environment

  • GFI LanGuard
  • All support versions

Solution

To test name resolution:

  1. Open command prompt in elevated mode (as administrator) on the GFI LanGuard server.
  2. Ping the client machine by hostname and verify which IP address is shown and compare with the IP address from that host under GFI LanGuard Dashboard.
  3. If the IP address does not  match, rescan the client machine using the Hardware Audit or Full Scan scanning profile, updating the IP address in GFI LanGuard for the client computer.

Cause

GFI LanGuard requires the resolution of the hostname to the corresponding IP address using IPv4 protocol to remediate a machine successfully. If GFI LanGuard is unable to resolve the client hostname to the corresponding IP address, the error network name cannot be found is displayed.

GFI LanGuard supports only IPv4.
