Webservice IIS and permissions 401 Error

Question

I have an issue I do not understand

I have a Webservices (not WCF) in two different locations, my localhost and our development server.

My localhost is running

XP SP3 IIS 5.1

Dev Server is running

Windows Server 2003 SP 2 IIS 6.0

Directory Security in IIS for Both is Anonymous Access and Integrated Windows authentication

My issue is when I run the following code from inside VS2010

Dim ws As RunExternalProcess.ProcessExecution = New RunExternalProcess.ProcessExecution
ws.Timeout = Convert.ToInt32(ConfigurationManager.GetConfigurationValue(KEY_VALUE_PROCESS_TIMEOUT_MILLISECONDS))
ws.ExecuteProcess (BusinessClasses.RunExternalProcess.enuProcessType.EFTCreateFile, PROC_POST, strParameters)

When the webservice is pointed to the Dev server it runs fine. When pointed to my local I get a HTTP 401 error

if I add the line

 ws.Credentials = System.Net.CredentialCache.DefaultCredentials

it works fine for my local. The question I need to answer before I deploy it is why do I need the credentials line if it works fine accessing the dev web service today. And what is different about my local?

Any Ideas?

Answer 1

You're probably not allowing anonymous access for your local server.

By default the client side copies the credentials/proxy settings of your Internet Explorer so you might want to check those too.

我还看到URL扫描也做一些奇怪的事情，如果您正在运行URL扫描，请检查这些设置是否阻止了它的访问。
