check dba_2pc_pending, there may be entries in there.

Oracle follows the 2-phase commit method when queries are submitted from stored programming units, it is default behaviour that cannot be changed.

We ran into this with a Web application that was doing remote querying, and Oracle said the only workaround for queries is issue a set transaction read only before the query is submitted.

(though maybe this isn't the problem at all for your situation... )

If on UNIX, running the oerr utility can be helpful to quickly find a bit more information about ORA errors: (I do not know, what's available on Windows).

df2hp105 [oracle] => oerr ora 2046
02046, 00000, "distributed transaction already begun"

// *Cause: internal error or error in external transaction manager.
//         A server session received a begin_tran RPC before finishing
//         with a previous distributed tran.

Check if there are any trace files generated to find any clues, else, open an iTAR (??).
