Cause

Insufficient rights on the remote task server registry key of "Hkey_Local_Machine\Software\Altiris\Altiris Agent\Servers". 

Resolution

In looking at the registry key as being an issue, it was found that the administrators were listed as having full control and read. No more rights were listed. After adding PowerUsers with read and special, System with full and read, and Users with read and running IISreset, the agents began to register. The remote task server in question was running IIS.

Another cause for the agent log error "Description: CAtrsException exception, error = "Unable to register", OS error = 2147549183, at line 440  re-throw at CTaskAgentBase::CheckRegister" would be if the asp.net is not installed on the task server.
