Root Cause

The access to the port of the global catalog 3268 is blocked.

Resolution

Ensure that the port for global catalog 3268 is open and accessible from the GFI MailEssentials machine. Verify whether there is a firewall which interferes the access from the GFI MailEssentials machine to the Domain Controller on port 3268.
