What is the problem?
You might see the license displayed in red and warning message - Server not found.
Your camera is unable to record the stream.
You are notified that you need more licenses to enable the camera recording.
Why did this problem happen?
Nx Witness software licenses are tied to a specific Server's HWID (Hardware ID).
If you've lost your licenses there is a high probability the computer that hosts the Nx Witness Server application where the licenses were originally activated has been modified in some way.
What is a HWID?
The HWID is a unique 34-digit identifier (example:03000102030405060708090a0b0c0d0e0f) generated when the Nx Witness Media Server is installed on a Windows, Ubuntu Linux, or ARM device. The HWID is based on a combination of software and hardware of the computing device upon which Nx Witness is installed.
The following items are used to generate a unique HWID for each computer upon which Nx Witness is installed:
- Network Card (NIC)
After installing Nx Witness on a server any modification in the software or hardware items above will result in a change of HWID and an invalidation of licenses attached to that device.
Most Common Reasons Your HWID Changes:
1. The NIC (Network Interface Card) Configuration on your computer hardware has changed.
- Physical Change: You've replaced a bad NIC.
- Software Change: You've enabled or disabled NIC ports, causing the existing NIC to no longer be recognized.
- HWID change due to NIC Troubleshooting Guide
2. The RAM Configuration on your computer hardware has changed.
- Physical Change: You've added or removed RAM (RAM in a computer is often made up of multiple physical RAM units. If one unit of RAM fails in a multi-RAM unit setup your computer may continue to work fine, but your HWID will be affected).
3. The Motherboard configuration on your computer hardware has changed.
- Physical Change: You've had a failed motherboard and had to replace it on the computer the licenses were originally assigned to. Changing the motherboard will result in a hardware change.
4. The BIOS on your computer hardware has changed.
- Software Change: In very rare cases a Motherboard BIOS update will cause the HWID to change.
