When reviewing the Application Event Log on a Microsoft Office SharePoint Server 2007 server, I noticed that I was getting six different error messages are regular intervals.

1. Event ID 7076 - Attempted to read or write to protected memory
2. Event ID 7076 - Exception from HRESULT 0x80005006
3. Event ID 6482 - Attempted to read or write to protected memory
4. Event ID 6482 - Exception from HRESULT 0x80005006
5. Event ID 6398 - Attempted to read or write to protected memory
6. Event ID 6398 - Exception from HRESULT 0x80005006

After scratching my head for a few minutes, I found a really simple solution. There is a hotfix for .NET 2.0 which seems to resolve all of the above error messages. The hotfix is documented in Microsoft KB923028, and it does not require a restart of the server. However, please understand that it will stop IIS and all of the services associated with SharePoint.
