ISA Server

Posted on 2006-05-17
Last Modified: 2010-07-27
I used to have an ISA server set up on a Windows 2000 Server machine.  About a year ago I uninstalled ISA server because we had purchased a new firewall appliance.  This server has recently been rebuilt under a Windows 2003 server OS and ISA was not reinstalled.  My problem is this.  When we had ISA up and running all of our client machines were set up to run through Proxy.  I will have local machines on restart (on a LAN) or if individuals take laptops home and then come back to the office on start up have their machines default to the old proxy settings of the ISA server.  How do i prevent machines from using this old proxy setting? (I know how to remove the proxy settings in the IE control panel, what i want to know is how do i prevent these local machines from ever receiving this information in the first place?) Would my primary domain controller server be sending the proxy server settings to the client machines?  And if so how do i change the settings so that it does not do this in the future?

Thanks in advance!

    Is there anything running in the logon script? Did any1 setup a GPO to use the proxy? Could you have a DNS setting somewhere? Have your checked for host files on the PC's? Just some starting points....

    OK, i checked the registry settings and found 1 instance of a proxy server setting on my PDC, I changed the default value so that it would not be active.  Hopefully this will correct my issue.  I'm going to try and follow up with some testing later this afternoon and tomorrow to see if this corrects the situation.

    I checked our logon scripts and all they are providing is mapping drives.  There was no GPO set up.  I reviewed the DNS settings and the gateway is correct and there are no listings for proxy.  The host file on a few pc's that i have checked are clean.  I'm going to check a few more pc registry settings and see if i can find further instances of proxy being set up on these pc's.

    I'll try and follow up early next week.

    I'm guess that the reg setting you found might clean up the issue.
