BlueCat - add DHCP WPAD option to all DHCP servers

Services Affected: BlueCat - add DHCP WPAD option to all DHCP servers

Start Time: 09/15/2018 11:00 pm

Maintenance Completed: 09/16/2018 2:16 am

Issue Symptoms: None

Windows clients request the DHCP WPAD option, but it is not currently defined, so they ask repeatedly. Defining it with a valid but not usable entry causes clients to stop asking DHCP, thus reducing unnecessary DHCP traffic and log lines.
