SQL Server Error: [8525] Distributed transaction completed.

I'm getting this error when synchronising a stored procedure that joins to a table on a linked server (sorry about the subject matter):



The following error message was returned from the SQL Server:

[8525] Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.

The following SQL command caused the error:

CREATE PROCEDURE spS_ChessLeague4 (
@Mode int
)AS

1 - Shows players who have played 5 or more games with an average of >= 0.5
2 - Shows players who have played less than 5 games or have an average of < 0.5
*/
