You can check the Squid logs to see what the problem is, but as a first thought I'd check to make sure the user account you're running Squid under for the service has the right permissions to what it needs. Try changing the service to run as Administrator or something to see if that helps, and then it's advisable to create a special account for squid with the permissions it needs to run squid under permanently. -----Original Message----- From: Giorgio.Bovio@xxxxxxxxxxxxxxx [mailto:Giorgio.Bovio@xxxxxxxxxxxxxxx] Sent: Monday, July 06, 2009 6:15 AM To: 'squid-users@xxxxxxxxxxxxxxx' Subject: The squid service on local computer started and then stopped on windows 2003 Good morning to all I have to install Squid on windows 2003 R2 Sp2.
