Resolution
This usually indicates an error with MSDTC. Kindly verify that DTC components are enabled on all servers where K2 server components are installed as well as the SQL server where the K2 db is sitting on (http://help.k2.com/onlinehelp/k2blackpearl/icg/4.6.9/webframe.html_Enable_and_Configure_DTC_Components.html). Also ensure that MSDTC and its port is allowed by the firewall (http://help.k2.com/kb001318)
