Web service in .NET project is initially unavailable unless anonymous access is granted.
I have an ASP.NET application developed in Visual Studio 2008 with VB.net and JavaScript.
In this app I have a master page with a link on it that when clicked calls a JavaScript function named YourAre(). This function calls a web service named HelpService that returns a string of HTML.
The problem is that if the user clicks on the link when first entering the app they will get an error message that says,
"Line: 54 Error: 'HelpService' is undefined"
If they navigate to another page or even refresh the page they don't get the error. If I give anonymous access to the web service by putting the following in the web.config file the error not longer occurs.
<location path="WebServices/HelpServ
<system.web>
<authorization>
<allow users="?" />
</authorization>
</system.web>
</location>
This happens on both my development machine and the production machine. This is an internal app and we use IE7 and 8, it happens with both. I've attached the HTML and JavaScript for the master page and the VB for the web service. Line 64 is the code for the link and line 112 is where the web service is called and the source of the error. Any assistance would be greatly appreciated.

Ignore that last post as it was supposed to be for another question.
I think there is no need of script manager to call a webservice.
