Remove Windows Security
The first step to establish DCOM communication is to disable the Windows Firewall, which is turned on by default.
The Firewall helps protect computers from unauthorized access (usually from viruses, worms, and negligent people or those with malicious intents). If the computer resides on a safe network, usually there is little potential damage as long as the Firewall is turned off for a short time.
Check with your Network Administrator to ensure it is safe to temporarily turn off the Windows Firewall.
To turn off the Windows Firewall, do the following:
- In the Windows search box on the taskbar, enter Windows Defender Firewall.
- Press ENTER.
- Select Turn Windows Firewall on or off.
- The Customize Settings window displays.
- Select Turn off Windows Firewall (not recommended).
- Click OK.
