John works as a professional Ethical Hacker. He has been assigned the project of testing the attacks. As a countermeasure, he suggests that the Network Administrator should remove the IPP printing…

DNS zone transfer attacks target misconfigured DNS servers that allow unauthenticated AXFR requests; they have no relationship to IIS or the IPP printing service.

SNMP enumeration exploits exposed SNMP community strings to gather network information; the countermeasure is restricting SNMP access, not disabling an IIS printing service.

IIS shipped with Internet Printing Protocol support enabled by default, and this component contained a well-documented buffer overflow vulnerability (addressed in Microsoft Security Bulletin MS01-023) that allowed remote code execution. Removing or disabling IPP from IIS eliminates the vulnerable code path, directly mitigating the IIS buffer overflow risk without requiring a patch.

NetBIOS NULL session attacks exploit unauthenticated SMB/NetBIOS connections to enumerate shares and users; the countermeasure involves disabling NetBIOS over TCP/IP or blocking port 139, not IPP.
