Environment

ITMS 8.1, 8.5

Cause

Usually these messages refer to one of these two common reasons:
1. Either you are missing the deployment plugin on the client, 
2. or the task server doesn't have the DSTaskhandler installed that it is connected to.

Resolution

The error message indicates a Deployment Solution task cannot be processed and the common cause for that is missing Deployment Plugin on the client or missing DS Task Handler on the Task Server this client is registered to. 

Plugin versions can be checked either from the Agent UI on the machines themselves or Plug-in Versions section of "Manage > Computers" in the Symantec Management Console (assuming the machines are otherwise reporting back to SMP properly).



The policies for the plugins are:

1. Make sure your client machine has the Deployment Solution Plug-in installed:

Agent Plug-in (client) install:
Settings > Agents/Plug-ins > All Agents/Plug-ins > Deployment > Windows (x64) > Deployment Plug-in for Windows (x64) > Install/Upgrade

2. Make sure the Task Server servicing this client(s) has the Deployment Task Server Handler installed:

Task Server components:
Settings > Agents/Plug-ins > All Agents/Plug-ins > Deployment > Windows (x64) > Deployment Task Server Components (x64) > Install/Upgrade


If the plugins are there, please verify that the versions match and upgrade if necessary:
KB 150933 "What are the released ITMS 8.5 Agent or Plug-in versions and build numbers?"

If that does not help please try reinstalling Deployment Plug-in on the client machine, or the entire Agent if the plug-in reinstall does not help.
