I just installed a router in place of MS Proxy 2.0 on a SBS 4.5. I updated DHCP with the correct settings. I uninstalled Microsoft Proxy Client from the workstations and disabled "use a proxy server..." The Internet then proceeds to work flaulessly. Then, when a user restarts their machine the option "use a proxy server..." is checked again and I have to uncheck in order to use the internet. How do I get rid of this! I have IE 5.5 SP1 with no web accelerators or Lotus notes. I went through and uninstalled manually Microsoft Proxy Client to double check through one of Microsofts articles. What else do I do???
