SharePoint Error For Reports - File Not Found. at Microsoft.SharePoint.SPSite..ctor

Experiencing a strange sharepoint error surrounding reports (moss 2007).

Recently we moved to a new development domain and rebuilt our sharepoint servers (with reporting services on the SP frontend).

Everything is fine apart from reports (which do exist), we get the following error when accessing them...

File Not Found.   
at Microsoft.SharePoint.SPSite..ctor(SPFarm farm, Uri req开发者_StackOverflowuestUri, Boolean contextSite, SPUserToken userToken) 
at Microsoft.SharePoint.SPSite..ctor(String requestUrl) 
at Microsoft.ReportingServices.SharePoint.UI.RSViewerPage.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) 
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) 

If I access them from sharepoint on the server itself, the report viewer works fine.

The only thing different to this install over any successful ones in the past is the domain itself.

We need to specify the full domain such as http://sharepoint.dev

Where in the past we've only needed http://sharepoint

With it working on the server, where we dont need to use the full domain only http://sharepoint, this suggests the fully qualified domain .dev could be the issue?

Does anyone have any ideas? Or how to get around this?

Cheers!

RSViewerPage.OnInit sounds like something hasn't been installed. Have the report viewer controls been installed?
