Brute force cracking solution based on NTLM plaintext authentication
The cause should be that a tool party authenticates through NTLM via TELNET, and the server responds to the request to crack the server's password.
Solution:
By disabling NTLM and LM responses, only NTLMv2 responses are supported.
Procedure:
Go to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Lsa in the registry.
Change the value of LMCompatibilityLevel from 2 to 5 by default.
