I checked this. I checked on the server, and nothing is using the drive letter. I also have another problem now. For my DHCP service, when I click on the server, it says that the service is not running. I have restarted, stopped, and started the service, reset the computer, and even reinstalled the DHCP service. Still nothing. This is interfering with my IIS, which says that it can't start because the address is already in use. I have already cleared out the ports that it uses and still nothing. WINS is also down. This is a fresh install of server, with SP4. I don't understand why all of these things are going wrong. WINS says the same thing: that the service is not running on the server.
