SYMPTOMS
After you establish a Dial-Up Networking connection and log on to the server using your domain user name and password, and you try to access a domain resource, you may be prompted to enter your domain user name and password or you may be denied access to the resource.



CAUSE
This problem may occur when your Internet service provider (ISP) credentials are incorrectly used for authentication instead of your domain credentials. Your credentials for the dial-up networking connection to the Internet are stored in Stored User Names and Passwords. This occurs when these credentials override your cached domain credentials that are also stored in Stored User Names and Passwords.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Windows XP service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

Note To install this hotfix, you must be running Windows XP Service Pack 1 (SP1). Windows XP Tablet PC Edition and Windows XP Media Center Edition include SP1. You must apply this hotfix and then re-create your Dial-Up Networking connections for this hotfix to work properly.



WORKAROUND
To work around this problem, use the Connection Manager Administration Kit (CMAK) wizard to create a custom Connection Manager profile for your Dial-Up Networking connection to the Internet. Make sure that you use the following settings in the profile:
 * Server&  (where  is the name of the dial-up networking connection entry)
 * Set the DontUseRasCredentials key to 1

The DontUseRasCredentials key specifies whether to cache credentials in Stored User Names and Passwords for use when accessing resources after logging onto the network. When you set this key to a value of 1, user credentials are not cached.
