Verify Domain of NI License Manager and Volume License Manager

For Volume License Manager (VLM) users, it is crucial to have the client's NI License Manager (NILM) able to connect to VLM successfully. There are several factors important for a successful connection such as:

1. VLM and NILM must be within the same domain.
2. Versions of VLM and NILM must be compatible with each other.
3. Ensure the server port is opened and more.

In this article, I will be sharing how to check are both VLM and NILM on the same domain.

Section 1: Getting IP Address and Computer Name of both the Server and Client

1. On server end, launch Command Prompt with administrator privilege.
2. Insert systeminfo and click Enter.
3. Jot down computer name. Computer name is the value of host name. 
4. In the same Command Prompt, insert nslookup follow with the computer name obtained on Step 3. For example, nslookup mypcname-00001
5. Press Enter.
6. Jot down the second address shown under Name parameter. 
   
7. Remember this pair of computer name and IP address.
8. Repeats similar steps on client end.

Section 2: System Domain Check

1. Launch Command Prompt at the server end with administrator privilege.
2. Insert nslookup following client's computer name.
3. Press Enter.
4. Check if the provided second address under Name parameter is similar to the IP address we obtained from Section 1. 
5. Repeat Step 1 to Step 3 at client end using server's computer name.

The expected result is server end should be able to come out with the similar client IP address after giving the client's computer name, and the same goes for the client end. If the correct computer name is not shown, it means either a computer with a similar computer name exists in the domain, but it is not the expected computer or it does not exist at all on the domain.
