To add/modify the reg entry through UI, can refer to the following screenshots:
If the environment doesn't have the registry entry called 'DisabledComponents', which is required and should have appropriate value can add the entry through the command line as mentioned in the article above or can use the regedit UI.
Please take backup of registry before any changes
Change the name to 'DisabledComponents':
Edit the value as per the requirement (refer the article). (Hex 20 for 'Prefer IPv4 over IPv6. Hex FF for 'Disable IPv6')
Note: Please make sure that the NFA console machine is restarted after the registry change.
Port 8981 has to be open on the NFA console machine for communication to happen between CAPC and NFA for NFA admin pages and SystemStatus.
