The DualShield Windows Logon Client is designed to be installed and running without the need for configuration by the user. Therefore, the logon client needs a way to automatically discover the logon agents.
The logon client will discover the logon agent by looking up a hostname called “dswagent2” or "dswsslagent2" in your DNS server. For instance, if the domain name of your organisation is “acme.org” then it will look for “dswagent2.acme.org” or "dswsslagent2.acme.org"
Therefore, you need to add these two hostnames to your DNS server.
If you have multiple logon agents installed, then you must add multiple entries of these two hostnames in your DNS server.
