Solution:

Navigate to C:\Inetpub\wwwroot\SightMax\WebServices, and open Web.config in Notepad.

Search for     <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> and replace it with:

<serviceHostingEnvironment aspNetCompatibilityEnabled="true">
<baseAddressPrefixFilters>
    <add prefix="http://YourWebsiteHostHeader" />
</baseAddressPrefixFilters>
</serviceHostingEnvironment>

Replace YourWebsiteHostHeader with the Host header of your Site ( Example www.sightmax.com ) then browse the SightMaxWebService.svc again.

Note: The HostHeader will be your Webservice URL.
