In Sophos Control Center, all computers are greyed out or have hourglass icons
I recently ran across this issue when installing Sophos Control Center on Windows Server 2008 R2, and the corresponding Sophos Endpoint Security on various client PCs.
After installing the Control Center, the PCs would never receive the central configuration from the server, and they never showed up as active in the Control Center. They were able to update, but used default configurations.
The solution was to open the following ports on the server’s firewall:
- TCP 8192
- TCP 8193
- TCP 8194
After opening the ports, the clients will begin to show up in the Control Center after 5-10 minutes.
For some reason the Sophos Control Center installer doesn’t open the ports for you. Also, this was my first Sophos installation on Windows Server 2008 R2, which has a fairly rigorous built-in firewall. The previous installation was on a Server 2003 system with a deactivated firewall, so we never encountered the issue.
A full list of ports for all of Sophos products is available here:
