link to oracle error

Hi
I am connecting from SQL server 2000 to oracle 9i.
I used following command and entry in tnsnames.ora file.
I am unable to run 2 select queries parallely from SQL server to oracle.
It throws me this error message.
I am amble to insert, delete. select from one connection without any errors.
Server: Msg 7399, Level 16, State 1, Line 1
OLE DB provider 'MSDAORA' reported an error.
[OLE/DB provider returned message: Oracle error occurred, but error message
could not be retrieved from Oracle.]
OLE DB error trace [OLE/DB Provider 'MSDAORA' IDBInitialize::Initialize
returned 0x80004005: ].

Presumptively, your Oracle server is e2.
1- We/I will need to see the tnsnames.ora entry- it is possible the
parameter should be 'e2.world' or similar and not just 'e2'
2- Is your %Oracle_Home% environmental variable set
3- is the Oracle Listener looking for the 'e2' as the service name on it's
server?
