How to reinstall the DHCP server role
Problem You uninstalled the DHCP server role and want to reinstall it.
Solution Run the Fix My Network Wizard (FMNW) three times to fix the DHCP server role. The first time that you run FNMW, the DHCP server role is installed. The second time that you run the FNMW wizard, it starts the DHCP service. The third time, the DHCP scope is created.
You do not receive a message after the first or second time that the FNMW is run that it needs to be run again.
For information about running the Fix My Network Wizard, see Fixing Network Problems.
