OPENQUERY Fails To Work With SP On Linked Server

Hello.
Suddenly OPENQUERY had started to raise an exception 'Msg 7355, Level 16, State 1, Line 1

The OLE DB provider "SQLNCLI" for linked server "sql2000" supplied inconsistent metadata for a column. The name was changed at execution time.'
The OPENQUERY stament looks like:


Code Block
SELECT * FROM OPENQUERY(sql2000, 'execute dbo.sc_List @AmountId = 24, @WorkMode=1, @SortMode=0')





I don't know what has been changed - seems that everyting is OK.
The problem is that sql2000 is MS SQL 2000 server and this statment is executed on the MS SQL 2005 server.
dbo.sc_List is a procedure that selects data and I need insert that data to the temporary table on the sql2005 server to make some calculations.
I've used OPENQUERY to prevent DTC coordinator from starting distributed transaction.
Whole statement originally looks like



Code Block
INSERT INTO #Templates SELECT * FROM OPENQUERY(sql2000, 'execute dbo.sc_List @AmountId = 24, @WorkMode=1, @SortMode=0')




where #Template is temporary table with columns that exactly match with stored procedure output.
Help me please - what is wrong with sql servers? I know that this query has been working fine for a months and now - such strange errors. I should say also that strored procedure returns always the same columns when called - there is one large select inside it.
Thank you.
