Content Database Schema conflict

MOSS 2007 Enterprise

We discovered the inability to get to our Central Admin site earlier. Were seeing SQL errors in the log files relating to schema versions not being the same. We applied SPS 3.0 SP2 and got our CA back. Now I am seeing the same SQL schema issues with our sites. Below is the error we are getting...

[SPUpgradeException: An error has occurred on the server.http://go.microsoft.com/fwlink?LinkID=96177]
   Microsoft.SharePoint.Administration.SPContentDatabase.ValidateDatabaseSchemaCompatibility() +1805

Anyone have some advice?
