The DualShield computer logon clients are designed to be installed and running without the need of configuration by the user. Therefore, the logon clients need a way to automaticaly discover the logon agents.
The way that the logon client locates the logon agent is by DNS lookup. The logon client will look up a hostname called “dsagent” in the domain's DNS server. For instance, if the domain name of your organisation is “acme.org” then it will look for “dsagent.acme.org”
Therefore, you need to add these two hostnames in your DNS server.
