Unable to begin a Distributed transaction

Can someone help me to troubleshoot this error? > Error:OLE DB provider "SQLNCLI11" for linked server "TESTSERV" > returned message "No transaction is active.". Msg 7391, Level 16, > State 2, Line 7 The operation could not be performed because OLE DB > provider "SQLNCLI11" for linked server "TESTSERV" was unable to begin > a distributed transaction. I am getting the error executing the code below. CREATE TABLE #Drive ( drive char(1) Primary Key, freespace int null ) Insert into #Drive EXEC TESTSERV.MASTER.xp_fixedDrives I've already done the following set up: Allow Remote Clients Allow Outbound On Security tab of Local DTC Properties in Component Services: 1. Go To Run, type comexp.msc. 2. Double click "Console Root". 3. Double click "Component Services. 4. Double click "Computers". 5. Double click "My Computer". 6. Double click "Distributed Transaction Coordinator". 7. Right click "Local DTC" under "Distributed Transaction Coordinator", and click properties. 8. Click the "Security" tab. 9. Put tick marks on the checkboxes "Allow Remote Clients" and "Allow Outbound". Still not fixed.
