Use the following procedure to configure the App-V Desktop Client for proper Windows Vista credentials.
This procedure must be completed on each non-domain joined computer. Depending on the number of non-domain joined computers in your environment, this could be a very tedious operation. You can use scripts and the command-line interface for Credential Manager to help administrators automate this process.
To assign the proper credentials for App-V clients running Windows Vista
With administrator privileges on the App-V Desktop Client running Windows Vista, open the User Accounts control panel (Classic Control Panel).
Select Manage your network passwords from User Accounts in the left tasks pane.
Select Add on the Stored User Names and Passwords screen.
On the Stored Credential Properties screen, provide the information for the App-V infrastructure:
Log on to: External name of the publishing server.
User name: User name for the external user in the form Domain\Username.
Password: Password for the user account entered in the User name field.
Leave Credential Type selected, and click OK.
Click Close. The credentials are stored in the credential store for proper authentication to the App-V infrastructure.
