SYMPTOMS

A computer that is running the Distributed Link Tracking Server service regularly issues a Domain Name System (DNS) query for the following Service Location (SRV) record:

_ldap._tcp.[Site name]._sites.dc._msdcs.ServerName

. In this SRV record, ServerName is the NetBIOS name of the local computer. For example, you may see a query on a new installation for the following record:

_ldap._tcp.Default-First-Site-Name._sites.dc._msdcs

The DNS query occurs approximately every four hours. If your DNS server is located over a dial-up connection, the DNS query may cause your server to automatically connect over the dial-up connection to complete the query.

CAUSE

This problem occurs because the Lightweight Directory Access Protocol (LDAP) interprets the local server name as a domain name.
