SYMPTOMS
When you deploy the Active Directory directory service in a distributed Microsoft Windows Server 2003 environment, you may experience heavy network traffic over the remote links. This problem occurs when the following conditions are true:
 * You have many remote sites.
 * Each site has a domain controller but no global catalog.

Typically, you may notice many remote procedure calls (RPC) to the global catalog over the remote link.



CAUSE
This problem occurs when the Windows Management Instrumentation (WMI) Windows NT event log provider uses a random GUID on a directory services call. When the Windows NT event log provider has to convert a GUID, the Windows NT event log provider calls the DsCrackNames function. If the DsCrackNames function cannot convert the GUID, the DsCrackNames function contacts the global catalog.

Note The DsCrackNames function converts an array of directory service object names from one format to another format.
