SharePoint Offline - Site is Down For Maintenance Feature

Sep 7, 2009 at 4:32 PM

Hi,

I installed the above application, and I'm getting the following error, when I go to Central Administration -> Application Mgmnt -> Set web application offline or online

Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified

I believe that the .NET Framework 3.5 SP1 is installed on our WFE server.

Thanks,

Rolando
