My setup was/is working fine; SquidNT 2.5 using ntlm_auth on Windows Server 2003. I have just setup a MS Vista client on the network and it is denied access (TCP_DENIED/407). If I remove the proxy settings from IE's on the Viata PC it can access the net fine. Is this a Squid problem or something else.
