Hello, I´m testing Squid 3 for Windows. I try to configure squid with ntlm authentication but I have a error in event viewer-Application. Type: Error User: NT AUTHORITY\SYSTEM Computer: LOBO Source: Userenv Category: None Event ID: 1054 Description: Windows cannot obtain the domain controller name for your computer network. (An unexpected network error occurred. ). Group Policy processing aborted. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. And the “cache .log” show this: ntlm-auth[2828](ntlm_auth.c:385): c:/squid/libexec/mswin_ntlm_auth.exe build Mar 6 2009, 23:32:18 starting up... ntlm-auth[2828](ntlm_auth.c:391): SSPI initialized OK
