Network License Server Does Not Supply Licenses to Client Computers

Install Icon


If you have followed all the instructions in the Network License Server Setup article and the license server does not supply licenses to client computers, any of these problems could be the cause.

  • Software or drivers on the client computers or server could be trying to use the same communications (com) port as the FARO license manager service (hasplms) causing port conflicts and stopping the server from supplying licenses.
  • The FARO license manager service could be stopped for some reason. There may be some thing or some rule in the IT environment that prevents the service from running.   
  • Com ports on client computers could be blocked by firewalls.

This article provides initial troubleshooting that identifies causes, but you may need help from your IT representative to finally resolve issues in your computing environment.


Time to Complete 30 minutes
Skills Needed
  • Knowledge of Windows at the operating system level
  • Familiarity with using command prompt commands
  • System Administrator skills
  • Knowledge of license servers
  • A functional Microsoft network server or a computer on a network to act as a license server
  • Installed and licensed FARO software on the client computers
Compatibility Click here to see FARO software compatibility with Microsoft Windows

Get Server and Client IP Addresses

  1. On the server, click the Windows Start button and in the Search field type Cmd, then press Enter. The Command Prompt window appears.
  2. At the command prompt, type ipconfig and press Enter.The IP address appears in the Wireless LAN adapter Wireless Network Connection: section on the line labeled IPv4 Address.
  3. Repeat steps 1 and 2 on the client computers.
  4. Record the IP addresses. 

Check if the Clients Can Communicate with the Server

  • On the client computer at the command prompt, type ping followed by a space and IP address, then press Enter.
    • If you successfully receive replies, the server does not have com port issues. Go to Check the FARO License Manager Service Status
    • If not, there are server com port issues that must be resolved before you can connect the client to the server. Contact your IT representative. 

Check if the Server Can Communicate with Clients

  • On the server at the command prompt, type ping followed by a space and IP address, then press Enter.
    • If you successfully receive replies, the client does not have com port issues. Go to Check the FARO License Manager Service Status
    • If not, there are client com port issues that must be resolved before you can connect the client to the server. Contact your IT representative.

Check FARO License Manager Service Status

Perform this procedures on both the server and clients. 

  1. At the command prompt, type netstat -aon|more and press Enter.
    A list of ports and their current states appears. 
  2. Locate the local address and record the PID that is listed. 
  3. Click the Windows Start button and in the Search field type taskmgr, then press Enter. The Windows Task Manager appears.
  4. Click the Services tab and sort the PID column ascending to descending. Look for the PID you recorded in step 2. The Name of that PID should be hasplms and the Status should be Running.
    • If the hasplms is not running, right click on the row and click Start Service. This may resolve the issue. But, when the computer is rebooted and you check the service again, if the Status is Stopped, there may be a rule or something in the IT environment turning off the service. Contact your IT representative. 
    • If the hasplms is running, but the server still does not supply licenses to the client computers, go to Check if Firewall is Blocking the FARO License Manager

Check if a Firewall is Blocking the FARO License Manager Service

  • Perform the steps to Check the FARO License Manager Service Status.
    • If the hasplms status is Running on the server and the client computers, but the server does not supply licenses to client computers, a firewall may be blocking communication between them. Contact your IT representative and ask that a firewall port exception be created for port 1947.
