- GFI MailEssentials
- All supported environments
When multiple applications use the same TCP remoting port, the first application that is launched gets exclusivity over that TCP port. When the second application tries to initialize using the same port, a connection refused error may be experienced. This is known as a port conflict.
- Open a command prompt (cmd.exe) and type
netstat -abn > c:\gfiports.txt
- Open gfiports.txt in a text editor and search for 8021
- Confirm which service is using this port. If anything other than a GFI MailEssentials service is running on the port, then it confirms that there is a port conflict between the GFI MailEssentials application and a third party application.
- Close all GFI MailEssentials applications (Configuration UI, Dashboard, etc.).
- Open the following GFI MailEssentials configuration files in a text editor and replace port 8021 with any new free port number (i.e. 8121):
- Open regedit.exe and navigate to:
- HKLM > Software > GFI >MailEssentials > Antispam > Config (x86 installations)
- HKLM > Software > Wow6432node > GFI > MailEssentials > Antispam > Config (x64 installations).
- Change the port number of 8021 to your new port number for the following keys:
- Re-start the GFI MailEssentials Managed/Antispam Attendant service.
- The GFI MailEssentials Dashboard application should now be operating on a remoting port other than 8021. If the Dashboard is still reporting that the Attendant service is not connected, reboot the server to ensure that the port change takes effect.
