I don't see your using statements so I'm not sure if you are pointing to the right namespaces or not.

ReportViewer1.ServerReport.ReportServerCredentials.NetworkCredentials = System.Net.CredentialCache.DefaultCredentials;
and
ReportViewer1.ProcessingMode = Microsoft.Reporting.WinForms.ProcessingMode.Remote;

A few others are confusing to me too. Anyway, follow this thread:

Is anonymous access for Report Services enabled or disabled? Check the different solutions (the fix depends on your network - is it a domain?)

Curious, why did you decide to start off with remote? Did you already do some local reports successfully?
