  1. After you choose a site, you can search the DNS SRV RRs to find all the local directories that serve the site:
    _ldap._tcp. site ._sites. domain
    site
    The name of a site identified in Locating the Site Objects in a Domain.
    domain
    The name of the DNS domain that contains the site.
  2. Convert the site name into DNS SRV RR format. For example, you can convert CN=SantaDominDiv,CN=Sites,CN=Configuration,DC=DOMAIN1,DC=COM into a DNS SRV RR format, _ldap._tcp.SantaDominDiv._sites.DOMAIN1.com.
  3. Use the Linux dig utility to search the DNS for directories that serve the site:
    dig +tcp -t SRV _ldap._tcp.SantaDominDiv._sites.DOMAIN1.com

    The dig command produces output similar to:

    <<>> DiG 9.2.4 <<>> +tcp -t SRV _ldap._tcp.SantaDominDiv._sites.domain1.com;
    ;; global options:  printcmd
    ;; Got answer:

    where the ANSWER SECTION lists the two directories that serve the SantaDominDiv site.

  4. Do one of the following:
    • If the ANSWER SECTION for the output lists one or more directories, go on to Configuring Site-Aware SRV Resource Records in TDGSS, and use the DNS SRV RR formatted site name you used earlier in this procedure.
    • If the ANSWER SECTION for the output of your dig command does not list one or more directories, redo the first two steps.
