Hi All, I have installed Squid 2.5 on NT M/c along with Intranet LAN & have been running it for last 1-2 yrs.. Now today I connected another Lan Card on the same M/c to connect to another ISP..Did setting as per requested & have started getting this error... The following error was encountered: Unable to determine IP address from host name for google.com The dnsserver returned: Refused: The name server refuses to perform the specified operation. Now even if I remove my new LAN Card..rebooted by machine...I am not able to use SQUID... In the access log I get Error : TCP_MISS/503 Please advice.. ____________________________________________________________________________________ The fish are biting.
