SYMPTOMS

When an application calls the CreateEnvironmentBlock function to retrieve the environment variables on a Microsoft Windows Server 2003-based or Microsoft Windows XP-based computer, the returned path environment variable is truncated to 1,024 bytes. This behavior occurs even though the maximum size of an environment variable is 2,048 bytes. This problem prevents the application from obtaining the correct environment variable.
