Enterprise Portal is not compatible with Microsoft XML version 3.0 service pack 4. You must run service pack 3 instead. This means that Enterprise Portal no longer works if you install Microsoft Data Access Components (MDAC) version 2.8. This may be a problem if you are running a product that automatically installs XML version 3.0 service pack 4, such as Siebel 7.5.2 client software.
