MVC 3 401 Unauthorized on hosting server

I have an MVC 3 application that is giving me a 401 error when I try and access it from the remote server, but when I run it from my local computer it runs with out any error. The remote server has IIS 7 configured to allow both Forms and Anonymous access and successfully serves static files (content files), it's only when I try and access the MVC application that I'm getting issues. When I browse to the MVC application, I get a prompt that says, "Windows Security - The server at requires a username and password. Warning: This server is requesting that your username and password be sent in an insecure manner (basic authentication without a secure connection)." I've tried entering all the passwords I can think of, and nothing give me access. When I click cancel, I get a server error that says, "401 - Unauthorized: Access is denied due to invalid credentials. You do not have permission to view this directory or page using the credentials that you supplied." and I've been redirected to the `LogOn` page My Web.config file looks like this: ``` <?xml version="1.0" encoding="utf-8"?> <!-- For more information on how to configure your ASP.NET application, please visit http://go.microsoft.com/fwlink/?LinkId=152368 --> <configuration> <configSections> <section name="razorJSSettings" type="RazorJS.Configuration.RazorJSSettings, RazorJS" /> </configSections> <connectionStrings> <!--<add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" />--> <add name="ApplicationServices" connectionString="Data Source=SOURCE; Initial Catalog=thedb; User ID=thedbuser; Password='thedbuserpassword';" /> <add name="GestmeDataContext" connectionString="metadata=res://*/Models.Gestme.csdl|res://*/Models.Gestme.ssdl|res://*/Models.Gestme.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=SOURCE;initial catalog=thedb;persist security info=True;user id=thedbuser;password=thedbuserpassword;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" /> </connectionStrings> <appSettings> <add key="webpages:Version" value="1.0.0.0" /> <add key="ClientValidationEnabled" value="true" /> <add key="UnobtrusiveJavaScriptEnabled" value="true" /> </appSettings> <system.web> <compilation debug="true" targetFramework="4.0"> <assemblies> <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> </assemblies> </compilation> <customErrors mode="Off" /> <authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" timeout="2880" /> </authentication> <membership> <providers> <clear /> <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" /> </providers> </membership> <profile> <providers> <clear /> <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/" /> </providers> </profile> <roleManager enabled="true"> <providers> <clear /> <add connectionStringName="ApplicationServices" applicationName="/" name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" /> </providers> </roleManager> <pages> <namespaces> <add namespace="System.Web.Helpers" /> <add namespace="System.Web.Mvc" /> <add namespace="System.Web.Mvc.Ajax" /> <add namespace="System.Web.Mvc.Html" /> <add namespace="System.Web.Routing" /> <add namespace="System.Web.WebPages" /> </namespaces> </pages> <httpHandlers> <add path="razorjs.axd" verb="GET" type="RazorJS.RazorJSHandler" /> </httpHandlers> </system.web> <system.webServer> <httpErrors errorMode="Detailed" /> <asp scriptErrorSentToBrowser="true"/> <validation validateIntegratedModeConfiguration="false" /> <modules runAllManagedModulesForAllRequests="true" /> <handlers> <add name="RazorJSHandler" path="razorjs.axd" verb="GET" type="RazorJS.RazorJSHandler" /> </handlers> </system.webServer> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="3.0.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-4.0.8.0" newVersion="4.0.8.0" /> </dependentAssembly> </assemblyBinding> </runtime> <razorJSSettings handlerPath="~/razorjs.axd"> <!-- If empty all paths are valid --> <allowedPaths> <add path="~/Scripts" /> </allowedPaths> </razorJSSettings> </configuration> ``` What are all the issues that could cause 401 errors to be returned from the server? Could it be the connection from the database to the server or the `aspnet_*` tables?
