When I want to the access SharePoint 3.0 Central Administration, web page gives the following error:
An error occurred during the processing of . Could not load file or assembly 'Microsoft.SharePoint.ApplicationPages.Administration' or one of its dependencies. The system cannot find the file specified.
I put the Microsoft.SharePoint.ApplicationPages.Administration.dll and Microsoft.SharePoint.ApplicationPages.dll files to the GAC.
I also tried restarting the IIS and recycling the application pools but it did not work.
