This article describes an issue where Patch Manager tasks against OUs may fail or run only partially. When this happens the C:\ProgramData\Solarwinds\PM\Log\EminentWare.WorkerProcess\EminentWare.WorkerProcess.exe.XXXXXX.XXXX.XXXX.log.txt shows the below error:

LDAPConnection::ctor unable to translate forest name to DS_FQDN_1779_NAME.
DnsDomainName: AnExampleADName.local.internal ForestName: AnExampleADName.local.internal Message: Object reference not set to an instance of an object.


Patch Manager versions earlier than 2.1.2


There is an empty OU in the task.


Identify if there are any empty OUs in the tasks having an issue. If so, either:

  • Remove the empty OUs from the task or
  • Add elements to the empty OUs
  • Upgrade to Patch Manager 2.1.2
