XPDTC.DLL - DTC transaction information

XPDTC provides a way to retrieve information about the fact if the current context in which the extended stored procedure (xp_dtc_tx_info) is executed, is part of a distributed transaction or not. When part of a distributed transaction, the XP can retrieve the transaction object and return the transaction ID which uniquely identifies the MS-DTC transaction, the transaction timeout and the transaction description.

This information is very useful when you need to troubleshoot distributed transaction and correlate transaction back to COM+ or MS-DTC based on the Transaction ID.
