Linked Server Fails after MDAC 2.8 upgrade

We installed the MDAC 2.8 upgrade and our existing
Microsoft OLE DB Provider for Oracle stopped working.
Other providers were fine, i.e. SQL Server (linking to
another mssql server).
Has anyone had this issue? Or does anyone have any
ideas as to what changed in 2.8 that would affect this
linked server?
Thanks in advance,
MarkI think that may be something related with distributed transactions.
I have some applications that stopped to work when I upgrade to MDAC 2.8.
Trying to solve this I discover that just returning the sql server odbc
driver files to version 2.7 the applications could work correctly... anyway
I think that is a bug in MDAC 2.8
