Description
Users reported license checkout failures, missing licenses, or timeout errors when connecting to the License Server. Investigation found that recurring scheduled restart tasks configured in Server Manager Console (SMC) were disrupting the License Server service and affecting its availability.
After disabling the legacy scheduled restart tasks and re-registering the License Server through SMC, normal operation was restored and clients were again able to obtain licenses. Continued monitoring is recommended to ensure long-term stability.
Solution
- Open Server Manager Console (SMC).
- Confirm that the License Server service is running.
- Locate any configured scheduled tasks related to License Server restarts and remove them by clicking red cross button. Click OK to accept the changes.Note: These tasks may have been implemented as a workaround for issues in older software versions and are no longer required.
- Reinitialize the License Server in SMC: Stop and then Start it.
- Validate licenses and connectivity:
- Ensure the license file is valid and licenses are listed in the License Server UI.
- Verify network/DNS reachability from clients to the server and that firewalls allow the license port. - Client validation:
- In client tools (Register.exe or acdnmon.ini), confirm the correct server hostname/IP and port.
- Restart the client application and confirm licenses are visible/usable.
