You are prompted for user credentials two times on a Windows Vista-based client computer when you access an online document that is on a site that uses Windows Live ID authentication

This article has been archived. It is offered "as is" and will no longer be updated.
On a Windows Vista-based client computer, you access an online document that is on a site that uses Windows Live ID (WLID) authentication. Then, you are prompted for user credentials two times. However, you expect to be prompted for user credentials only one time.
The Microsoft Office Live Workspace client uses WLID to access the online document. Office Live Workspace uses two networking stacks for communicating with remote servers. Credentials are not transferred between the stacks. Therefore, the user is prompted for user credentials multiple times.
Note After you apply this hotfix, Windows Vista stores WLID credentials for the Windows session. Therefore, credentials can be transferred between stacks.
