After scheduling a task clients immediately fail with Unable to get a .NET type error message
This error will come up when attempting to execute tasks on already upgraded client that registered to not yet upgraded Task Server” (i.e. client version > than Task Server version)
The agent software package within the Policy has been updated. However, the Policy GUID appears to have remained the same.
This means that the servers never obtain a "new" policy to execute on the Run Once ASAP schedule.
Upgrade the Task Server to the correct version.
Check to make sure your Task Servers are up to date as well. The upgrade policy is in Settings > All Settings > Notification Server > Site Server Settings > Task Service > Advanced.
The Task Server upgrade policy will only apply to a server if the Management Agent is on the latest version as well. In addition to checking the Task Service upgrade policy, check the Agent Upgrade policy in
Settings > All Settings > Agent/Plug-ins>Symantec Management Agent>Windows>Site Server.
After upgrade to Latest HF for NS 7.5:
Add a new schedule to the policy and save it and update the agent policy on the task servers.
Wait for filters and collections to be updated.
After uploading the new inventory the client should not take more than an hour to be functional again. Usually the change is less than 15 minutes.
After upgrade to latest HF for NS 7.5, where the Task Server service has not been upgraded yet. Altiris Agent has usually been upgraded on the Task Server.
Result is that the Task Server is running the latest Altiris Agent but not the latest version of Task Server.
