Look it up in the NTP controls for your machine. Squid works on whatever the OS says the time is. Also check all the other time related settings on the box (timezone, local vs universal, hardware clock settings etc) to make sure they are right. One common mistake is to set the HW clock to universal time and setting the OS to thinking its running HW clock in local time. Or the opposite. > 2) If #1 can be fixed I am not sure the times I have set are working and > being blocked This is statement. not a question. invent some tests.

Yes. Create an ACL for normal login. Adding it to the end of the line For example: ... login setup acl loginACL proxy_auth REQUIRED http_access deny our_networks bad_url workdays !loginACL > 4) Most users here use sharepoint and I cant seem to get IE to get the > authentication prompt.

Please explain? DNS does not depend on HTTP. More the other way around. Amos
