Windows Media Services provides support for Simple Network Management Protocol (SNMP)-based management consoles through an extensive set of SNMP objects. These objects are defined in the Windows Media Services SNMP management information base file WMSSNMP.mib, which is located on your Windows Media server in %systemroot%\System 32\Windows Media\Server.
To use Windows Media Services SNMP objects, you must first register the DLL Wmssnmp.dll. For more information about registering the DLL, see To register Windows Media Services SNMP objects for SNMP monitoring.
It is recommended that you configure your server to use Internet Protocol security (IPSec) for SNMP data transfers. Otherwise, the SNMP service will transfer data in clear text, which means that the data could be intercepted and decoded by network analyzers. IPSec encrypts data and communications between the SNMP agent and management stations, so the information is safer from interception.
If you decide to use IPSec for SNMP data transfers, you should create an IPSec policy on your computer that filters data transferred on both UDP and TCP ports 161 and 162 and that uses Kerberos authentication. For more information about creating Internet Protocol security policies, see Windows Help and Support.
The following table lists the objects that you can receive in your SNMP browser. All of the objects have read-only access.

Note
SNMP services are not installed by default with either the Windows Server 2003 operating system or Windows Media Services. Before attempting to use Windows Media Services SNMP objects, ensure that SNMP services are installed on your computer. For more information about installing SNMP services, see Windows Help and Support.
