Update 22-Sept-2016
Using VMware Workstation Player 12.5.0? Please download vmnetcfg.exe for v12.1.0 below and copy/paste it into your Program Files (x86) folder. It will work just fine.
>> Note: the extraction command no longer works from version 12.x onwards. If you want to obtain the vmnetcfg.exe file yourself instead of downloading it from here, you will have to:
- Download and install VMware Workstation Pro 12.x.
2. Copy the vmnetcfg.exe file from the “Program Files” folder.
3. Uninstall VMware Workstation Pro 12.x.
4. Install VMware Workstation Player 12.x.
5. Copy the vmnetcfg.exe file you saved to the “Program Files” folder.

Update: 23-April-2014
>> If you have, for example, VMware Player 6.0.2, you must use the vmnetcfg.exe and vmnetcfglib.dll files provided specifically for version 6.0.2. All I ask of you my dear reader is to request for new files in the comments below every time you need updated files when VMware releases newer versions such as 6.0.3, 6.0.4, and so on, in the future.
Explanation
I obtained those two files from VMware Workstation 10 using:
C:\Downloads>VMware-workstation-full-10.0.1-1379776.exe /e extract
Then I looked for core.cab file and extracted vmnetcfg.exe and _vmnetcfglib.dll from it. Then I renamed _vmnetcfglib.dll to vmnetcfglib.dll (removed underscore).
Now in your case, this is the only thing you have to do:
Copy the two files vmnetcfg.exe and vmnetcfglib.dll to your VMware Player directory which resides in Program Files or Program Files (x86).
For example, copy to the following path:
C:\Program Files\VMware\VMware Player
Then run vmnetcfg.exe and you will see the following… and you know what to do next 🙂 Thank you for reading!
