Issue/Introduction

The Enforce console displays a Code 3900 Internal communications error.

Cause

This was caused by deleting two detection servers from the Enforce console but not uninstalling the Detection server software from their host server.
When the deleted Detection servers try to contact the Enforce server, this error will be created.

Resolution

To resolve this error, uninstall the Detection server software for those Detection servers that have been deleted from the Enforce server.
