Service Principal Names (SPN) can be constructed only by using the account base name as the second part. The directory service enforces this, by generating a constraint violation error. You may not have the rights to access or modify this property on some account objects. You can determine what your access rights are by viewing the security attributes on the account object using the Directory Management (Active Directory Users and Computers) Microsoft Management Console (MMC) snap-in, a Windows 2000 administrative tool.
When reporting bugs or making requests (such as feature requests), include the following information:
