Is there a possibility to install and use the Client Test tool on a machine that is not hosting DataMiner?
Yes. You need these files:
Copy them from the server (Skyline DataMiner\Files) to your client, and you should be able to run SLNetClientTest.exe.
Note: the files needed to run SLNetClientTest.exe can change in future versions. When a file is missing, an error message will pop up that should indicate which file you need. Alternatively you can run the tool from the server, connect to a DMA, and check with Process Explorer which files are used:
Thanks Lander for the response.
You can also just copy over the complete Files folder.
