I have an appliation that makes use of sharepoint web services that is running on the same server as my sharepoint installation. I was using computername:portnumber to access the site, but assigned a 'friendly' URL on my DNS server for users to use. This 'broke' my app that accesses web services. I am now getting 401-Unauthorized. Anyone have any ideas as to why this is happening because of a URL change?
