In fact, the services provided are standardized
across all operating systems as part of RFC 2782 (see http://www.faqs.org/rfcs/rfc2782
.html for details). You??™ll normally use this script feature on domain controllers only. The DNS
Service (SRV) records have both a priority and a weight. The priority affects the LdapSrvPriority
registry setting (see http://www.microsoft.com/technet/prodtechnol/windows2000serv/
reskit/regentry/55945.mspx for details). When two DNS servers have the same priority setting,
Windows relies on the weight setting to determine which server to use. You set the priority using
the /DP command line switch. This script feature uses the following syntax:
/DP [/v][Value]
The following list describes each of the command line arguments:
/v Displays the current DNS SRV priority setting.
Value A value between 0 and 65,535 that defines the server priority. Microsoft recommends a
value of 200.
As previously mentioned, when two DNS servers have the same priority, Windows relies on
the weight value to determine which server to use. Use the /DW command line switch to modify the
DNS SRV record weight. This setting affects the LdapSrvWeight registry setting.
