Issue

The following error appears when trying to deploy using MMC Package and Deployment tool:

System.Reflection.TargetInvocationException: C:\ProgramData\Temp\c4e8b8003ae64541b933e26a5880869c\Deployment\K2Project3.msbuild(82,5) : error : Notification Service: Task Error: Primary Credentials Not Authenticated

Symptoms

This issue could be caused by an incorrect value for the "ServiceObject Server" and "SmartObject Server" Environment Fields. Check if the connection string is missing  the "IsPrimaryLogin=TRUE" parameter/argument.

Troubleshooting Steps

Correcting the value of the connection string for those environment fields will resolve the issue.
