Reoccurring WAN traffic every five minutes may cause high line costs

If you have a trust across a wide-area network (WAN) line, you may notice that the WAN line is used every five minutes. If you trace the traffic, you see remote procedure call (RPC) requests that contain an "Authenticated Users" string in the data portion. If you perform a full trace, including the connection establishment, you see that the RPC requests go to the LSASRV pipe. This behavior occurs if you are running a Windows 2000-based forest with multiple domains with a non-English version of Windows 2000. You also have Domain Name System (DNS) servers running in each of the domains.

The DNS server checks the security settings on Active Directory objects and builds a security identifier (SID) object for the "Authenticated Users" account. Because this special group name is translated in localized versions of Windows 2000, it is not found in the local built-in database and is forwarded to all the trusted domains.
