Hi, can anyone help with this pls - it's getting very fustrating! there seems to be some messages and text on this issue (looks like a common problem that MS haven't published anything about yet!) but nothing I could make heads or tails off... so any help here would be very useful! I'm using VS2005 (release, NOT beta), the new reportviewer web control and an ASP.NET page - really basic, nothing fancy. I've set the reportviewer properties to: ReportServerURL= http://mytestserver/reportserver ReportPath = /AdventureWorks Sample Reports/Company Sales I'm testing the ASP.NET page is on my local machine - and the reportviewer isconnecting to a remote test server (W2k3 SP1). When I view the page, then I get HTTP ERROR 401 Unauthorized Directory Security on the report server is Windows Authentication - W2K3 with SP1 and Reporting Services 2005 (release, NOT beta) Directory Security on my local machine is Windows Authentication - XP SP2 and VS2005 (release, NOT beta) Any ideas pls?

btw: the version of the report viewer I'm using is the new one that comes with VS2005 (Microsoft.ReportViewer.WebForms) the previous version of the reportviewer control (Microsoft.Samples.ReportingServices) worked! any help would be greatly appreciated
