TCP/IP NAME RESOLUTION (DNS)
These settings affect how SurfControl Web Filter resolves Domain names:
• Workstation name resolution - Determines a workstation name based on IP address.
• Site name resolution - Provides DNS resolution for destination names.
SurfControl recommends you leave these settings cleared to increase performance. If you need
workstation and site name resolution enabled, you must define the DNS settings on all Web Filter servers.
It is critical that DNS requests from those servers do not time out or take an excessive time to respond.
MONITOR TO DATABASE SETTINGS
By default the Web Filter service writes data to flat files, which are then imported to the database
automatically. The Monitor to Database settings enables you to configure this process. The options are:
• Automatic (default setting) - Flat files are continuously imported into your database as they are
created.
• Manual - Select this option to update the flat files to your database manually. This can be done in the
following two ways:
–Use the Database Updater tool. See "Updating Your Database" on page 134 for more details.
– Schedule a database update event in the Scheduler. See "Database Update" on page 143 for
more details.
SurfControl recommends using a scheduled event for updating your database. This ensures that your
database is automatically kept up to date, without the need to perform a manual update.
