I have couple of servers with SQL Server 2000 on windows 2003 SP1.
Simulate scenario
-- Run on SQLSERVER2
BEGIN DISTRIBUTED TRANSACTION
select * from SQLSERVER1.pubs.dbo.sysobjects
COMMIT
When I am using above linked server query to fetch data from one server and insert data to local server following SQL error is returned.
[OLE/DB provider returned message: New transaction cannot enlist in the specified transaction coordinator. ]
OLE DB error trace [OLE/DB Provider 'SQLOLEDB' ITransactionJoin::JoinTransaction returned 0x8004d00a].
Msg 7391, Level 16, State 1, Line 2
The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction.

Please note
1) MSDTC is configured to allow Network DTC Access
2) There is no firewall between the servers

Gopal ,

Have you rebooted the servers? MSDTC should be enabled on both servers.

You may want to give this a try. If this does not work, let me know, there is a work-around, without using Distributed Transactions, but this will depend on the requirements.

MSDTC was configured long time back and servers are rebooted couple of time after the configuration.

Please post the work around.

Gopal,

Note: After re-evaluating your posting, I am assuming that your original code was something like this.

Possible Problem:[/u]

INSERT DestDB.dbo.Table

select from SourceServer.SourceDB.dbo.Table

--NOTE:** Something like this will require Distributed Transactions to be fully functional.

Sample Work-around Code using Temp table as a temporary placeholder[/u]

if (exists (select 1 from tempdb.dbo.sysobjects where name like '%Mengus%'))

begin

drop table #Mengus

end

-- Grab data from Linked Server/Database (Source)

select

*

INTO #Mengus

from LinkedServerSource.master.dbo.sysobjects

-- Transactions when applicable....

-- Then INSERT DATA FROM Temp Table into Local Database

--......

-- Handle Transaction (Rollback/Commit) when applicable

Actually the original code looks like as follows

INSERT INTO DestTable

EXEC SourceServer.database.dbo.usp_returnOneRecordSet

I don't have choice of editing code of source server.

Gopal,

*** Check this old forum post:http://www.sqlservercentral.com/Forums/Topic200830-8-1.aspx

Regarding your comments:

If that's the case, temporary tables will not work. I have tried it for a couple cases. However if you rewrite the logic and convert the stored procedure to an actual SELECT statement, you can use temporary tables and "SELECT INTO."

Example:

Instead of

INSERT INTO #temp

EXEC SourceServer.database.dbo.uspSproc

Must be converted to:

select

--Appropriate Columns (as returned by stored procedure)

INTO #temp

from SourceServer.database.dbo.Table

Thanks. I am aware of this kind of approach but I don't have option to modify code on source server.

BTW Does anybody know of real cause of this problem.
