trigger - Sql2008 - Msg 7391 - "no transaction is active/unable to begin trans"
FIXED!

Every site has the same step-by-step.


  
  Start 
  DCOMCNFG 
  Expand "Component Services" 
  Expand "computers" >
  Expand "My computer" 
  Expand "DTC" 
  right click on "Local DTC" 
  Properties 
  Security  check  "Network DTC Access" and " allow remote clientes".
  


It for sure will help a lot of people. The problem is that the server is in a cluster, so what a did is:


  
  Start 
  DCOMCNFG 
  Expand "Component Services" 
  Expand "computers" >
  Expand "My computer" 
  Expand "DTC" 
  Expand "CLUSTERED DTCs" &lt;&lt; This is the trick 
  Right click on the server and make the same config as above for the "local DTC"
  


Restart service. Enjoy you boss Happy.
