PRB: Cannot Install Commerce Server 2002 Developer Edition on Windows XP

When you try to install Microsoft Commerce Server 2002 Developer Edition on a computer that is running Microsoft Windows XP, the installation fails.

During setup, service accounts are configured. Each Service Account has a user name, a password, and a domain name. After this operation, you receive the following error message:

This problem occurs because the computer is not a part of a domain (in a peer-to-peer network). Commerce Server 2002 Setup uses Security Support Provider Interface (SSPI) to do a network-style logon by using the provided user credentials. This type of validation does not require the current user to have any special rights. Also, this type of validation works on all versions of Microsoft Windows. However, on Windows XP, the ForceGuest registry value is set to 1.

On a computer that is running Windows XP, and that is a member of a workgroup:

• If ForceGuest is enabled (set to 1), SSPI always tries to log on by using the Guest user account:
  • If the Guest account is enabled, an SSPI logon will succeed as Guest for any user credentials.
  • If the Guest account is disabled, an SSPI logon will fail regardless of whether you provide valid credentials.
  This is the default behavior on Windows XP in a peer-to-peer network.
• If ForceGuest is disabled (set to 0), SSPI logs on as the specified user.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this problem, set the ForceGuest registry value to 0 in the following registry key:

This behavior is by design.
