Problem
BTSSvc$BizTalkServerApplication has a dependency on the Enterprise Single Sign-On Service (ENTSSO) and may timeout during start up after a reboot.
Cause
The Enterprise Single Sign-On Service may take around 3 minutes to start.
Resolution
Configure the “BizTalk Service BizTalk Group: BizTalkServerApplication” service with the Automatic (Delayed Start) startup type option. This will initiate the start of the service after all Automatic services have completed their startup routines.
