1. Problema na autenticação NTLM

Bom dia,Tenho um squid fazendo autenticação nos grupos do AD. Depois de muitos testes, constatei que a queda da internet, que ocorre de forma intermitente, esta relacionada a autenticação NTLM que uso para autenticar os grupos do AD. Caso eu comente as linhas de autenticação, a navegação transcorre normalmente sem nenhum tipo de problema.
Como posso resolver isso?
Segue meu squid.conf abaixo.
Quem puder ajudar, agradeço!
