On the Round Robin DNS page, you can configure whether the NetMan Web Service adds DNS entries in the DNS server:
Activate round robin DNS support. Activates support for the round-robin DNS method.
DNS zone. Enter the DNS zone here (example: host.mydomain.local).
IPv4 host name. Host name of the cluster host (IPv4) for the session hosts that take part in round-robin DNS (example: MyClusterHost).
IPv6 host name. Host name of the cluster host (IPv6) for the session hosts that take part in round-robin DNS (example: MyClusterHost).
Number of session hosts registered (in %). Indicates the percentage of session hosts stored per host name. If you enter "60" for example, only 60% of all session hosts are registered. Before the servers are registered, load balance is calculated as defined on the Load Balancing page, and only the less utilized servers are designated. If you enter 100%, all servers are registered in the DNS, and load balancing is not implemented. If a session host becomes unavailable, it is automatically removed from the round-robin list.
Intervals at which DNS entries are updated (in seconds). The host entries are updated at regular intervals, the length of which you can define.
DNS server is on the NetMan server. Select this setting if the DNS server is on the same server as your NetMan Desktop Manager installation.
DNS servers are on other servers. Select this option if there is no DNS server installed on your NetMan server and you have one or more separate DNS servers in your network. In this case you need specify the server and the login data so NetMan Desktop Manager can still use round robin DNS for load balancing.
If the DNS server is not on the NetMan server, you have to specify an account, a domain and the required password in addition to the DNS server name. The account has to have sufficient rights to set the DNS entries on the DNS server via WMI (for details see the Microsoft MSDN article, "Securing a Remote WMI Connection"). For details on creating such a user account, see "Load Balancing/In Thin Client Environments/Round Robin DNS".
<n> DNS server(s). Enter one or more DNS servers in this list.
WMI login
Account. A user account with sufficient rights to set DNS entries via WMI.
Domain. The domain of the above user account.
Password. Password for the user account.
Server farm. Select the NetMan server farm that implements load balancing.
