Rebuilding the Connection Between Forcepoint DLP Endpoint Clients and Endpoint Servers
A mismatch between CA.CER files between the Endpoint Server and Clients will cause them to be disconnected. The steps below will help you recreate the CA.CER file on Endpoint Clients.

Note See the internal article PS: Replace Certificates on DLP Endpoint Servers for a Professional Services procedure to update the certificate on customer environments.

CHANGELOG:
Reviewed by Matthew Perrott 25/08/2015 - no changes required
Timothy Riegler 1/10/2020:
Resolved issue running cert.vbs in some environments where DisableAntiTampering takes longer to process than the script runtime. The error is a VBScript Permission Denied CODE: 800A0046

Added this to line 130 of the script:

WScript.Sleep 3000 'Sleeps for 3 seconds

This allows for the script to wait for disableAntiTampering to complete. The value can be edited to any wait period. Value is in milliseconds.

Also changed the applicable versions for this KB as it has been shown to work on all Windows based Endpoints.
Removed references to EI-728, as this appears to point to something unrelated.

07/19/2021 - Corrected typo for case sensitive link: https://<EPServer IP>/EP/EndpointServer.dll
