Access Violation in ole32 dll after installing MS09-012 on Windows 2000 servers

  • Article

On windows 2000 SP4 machines, you may experience AVs (C0000005 exceptions)  in SQL Server or any application using msdtcprx.dll after installing the update MS09-012. This is seen only on the machines with ole32.dll version earlier than 5.0.2195.7036

You will not see this issue if the server has Microsoft security bulletin MS06-018 OR COM+ rollup 32 OR subsequent rollups

Workaround

To avoid running into this issue, install MS06-018 OR COM+ rollup 37 prior to installing MS09-012

More information

An access violation (C0000005) occurs if you call the CoWaitForMultipleHandles function before you call either the CoInitialize function or the CoInitializeEx function. This is first addressed in COM+ roll up 32
