- 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.
- Convert the site name into DNS SRV RR format. For example, you can convert CN=SanDiegoHQ,CN=Sites,CN=Configuration,DC=DOMAIN1,DC=COM into a DNS SRV RR format, _ldap._tcp.SanDiegoHQ._sites.DOMAIN1.com.
- Use the Linux dig utility to search the DNS for directories that serve the site:
dig +tcp -t SRV _ldap._tcp.SanDiegoHQ._sites.DOMAIN1.com
The dig command produces output similar to:

where the ANSWER SECTION lists the two directories that serve the SanDiegoHQ site.
- 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.
