I just discovered that some weeks ago Microsoft released a cumulative upgrades of hotfixes for Analysis Services 2000 released after SP4. I have to say that I noted AS2000 is less stable after SP4 intallation (I can say that after months of use) and I randomly got event ID 132 that appears to be resolved by SP4 but I’ve never seen before SP4 (btw, it seems that a pretty invasive backup program lock a file that should be deleted when this happens, so it should be not a SP4 responsibility). I have no time to open a call to Microsoft Support (it’s a very expensive process) – I hope Microsoft will improve the way a user can submit a bug (service shutdown seems to be a good candidate) in a production system…
An equivalent post-SP4 cumulative upgrades of hotfixes is also available for the relational part of SQL Server 2000.
