Hi,

      As we are having 3 WFEs. When user tries to access URl following error message appears

A Web Part or Web Form Control on this Page cannot be displayed or imported. The type Microsoft.ReportingServices.SharePoint.UI.WebParts.ReportViewerWebPart, Microsoft.ReportingServices.SharePoint.UI.WebParts, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91 could not be found or its is not registered as safe

I am working on Support project. Kindly provide a feasible solution as earlier.

Regards,

Abdul

Hi Abdul, 

it seems that is missing the registration of your webpart, in sharepoint application webconfig. this should be an automatic procedure.

are you seeing this in all front ends?

Try to re-install your WSP package.

Yes. I am seeing the same error in all 3 WFEs.

Which WSP package needs to get installed. Please provide some more precise information.

As I am new to sharepoint environment
