The program %2, with the assigned Process ID %1, supplied a NULL or empty target name for the pszTargetName parameter when calling the InitializeSecurityContext API to initiate an outbound NTLM security context. This is a security risk when mutual authentication is required.
 
 To help protect against a malicious attack, make your code more secure. To do this, change the program so that it specifies a target name in the pszTargetName parameter field, and then recompile the code.
