sql2000 - sp4
I have a problem on my production box and test where I have a linked server to an Oracle instance. The linked server works fine until I issue a distributed transaction around the statement.
When I do I receive the below error going to a prod and test oracle instance
Server: Msg 7391, Level 16, State 1, Line 2
The operation could not be performed because the OLE DB provider 'MSDAORA' was unable to begin a distributed transaction.
OLE DB error trace [OLE/DB Provider 'MSDAORA' ITransactionJoin::JoinTransaction returned 0x8004d01b].
If I run a distributed query thru a linked server to a sql box everything is fine.
I am positive MSDTC is fine.
I was contemplating dtc ping but the proc it runs I traced and see it actually cycles thru for 50 minutes then fails ?? So how could it be a firewall issue ??
Any help would be appreciated !!

there is a primary key on both sides?

YES the one oracle table has 2 PK keys.
SQL server side where it deletes from 18 tables does has a primary key on every table but maybe half on the same column/columns as oracles keys.
UPDATE: We actually kept rerunning it and it finally completed successfully. Yet when I issue begin distributed tran it still fails.
Go figure ?

Could it be the new security settings for MSDTC in Windows 2003?
