Issue



When the Notification Server is restarted, many of the client machines experience the following problems:
  1. Unable to re-register with their Task server (The NS itself) even when "Reset Agent" is used.
  2. NSE's build up in the Event Queues (Unable to send them to the NS)

The following messages are seen in the Agent log:

Environment



Symantec Management Platform 7.0 SP4 (First noticed)
Task Server 7.0

Cause



Proxy Server is interfering with Agent communication

Solution



There are 2 possible resolutions to this issue:

Resolution 1: Stop the NS Agent from using the Proxy Server

     To do this, follow the resolution for Scenario 2 in KB 43801 


Resolution 2 (Non-Symantec Solution): Make adjustments to your particular flavor of Proxy Server to better facilitate communication between the NS Agent and the NS itself. Every proxy server is a little bit different. Consult the vendor documentation to see what configuration changes can be made.
