I installed sbs 2003 with one network card. A couple of months later I added a second network card and everything went wrong. I have had to disable the Remote Access and Firewall for any communication to the server. Is is possible to apply a repair installation to SBS 2003, and if it is will it keep all the user and exchange data. I would like everything to go back to default, but I didn't want to start from scratch and have to bring all the user data into a new installation. If bringing the data over to a new installation is the only way I can do that also...Thanks.
