Help! Oracle linked server not working

we upgraded servers and now i can't link to an oracle server
old config:
windows2000
sql2000 sp4
mdac 2.8
oracle client 9.2 with latest patches
new config:
windows2003
sql2000 sp4
mdac 2.8
oracle client 9.2 with latest patches
the oracle db is 9.2.
i get the error 7399: OLE DB provider 'MSDAORA' reported an error.
OLE DB error trace [OLE/DB Provider 'MSDAORA' IDBInitialize::Initialize
returned 0x80004005:]
i've scoured the internet and found numerous solutions to this, none of
which work.
i found an article in oracle technet that said to redo all permissions
on the oraclehome
directory. that didn't work.
i made sure the registry entries pointed to the correct oracle dll's.
no help.
i tried the 10g client with latest patch. no help.
i deleted and readded the linked server. no help.
i can use sqlplus or netmanager and connect to the oracle db just fine
from the sql server.
i don't know what else to try.
i'm wondering if it's windows2003 that's screwing things up.
has anybody been able to link to an oracle server from a win2003 server
running sql server sp4?Some additional questions:
What platform is the Oracle database?
Is connection pooling being used?
What language is doing the call or are you doing linked servers (four level
table qualifier)?
That particular error has a lot of possibles, as you found. Don't want to
re-hash what you have already ruled out.
