Sharepoint 2010 - When working on a document credentials are requested constantly

When you are working on a Sharepoint Site you find that you are asked for your Domain credentials constantly, this is more apparent when working on a document.

Create a New Document

When you are in the Sharepoint Site you choose to create a New Document.

Credentials Window

You are now asked for credentials even though you have logged onto your computer with the right credentials. This is because you are using Windows Vista or Windows 7 and the Sharepoint site is a FDQN such as sharepoint.cscmhosting.co.uk rather than http://sharepoint. Windows thinks the site is on the Internet as as such wants you to authenticate.

Registry Edit

You can edit the registry to change the behaviour to allow your Sharepoint Site. Browse to the key

Compuer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servcies\WebClientaParameters

Create a new Multi String Key

Create a new Multi String Value

Key Name and Value

Create the Multi String Value

AuthForwardServerList

Then add the name of your Sharepoint Site FQDN

Restart the WebClient Service

Restart the WebClient Service to enable the change and now you will be able to create a New Document and not have the credentials dialog.
