Network Location Awareness (NLA) (System Services for the Windows Server 2003 Family and Windows XP Operating Systems)

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

Service Name: Nla

Executable Name: svchost.exe -k netsvcs

Log On As: LocalSystem

Description: The Network Location Awareness (NLA) service collects and stores network configuration information such as changes to the names and locations of IP addresses and domain names, and notifies applications when this information changes. The NLA service component supports the Network Location Service. This component provides the infrastructure that informs applications and the operating system of the network connections on a specific computer. This component implements the NS_NLA Windows Sockets namespace.

This service will automatically start when the startup type is Manual.

If this service is disabled, NLA functionality is not available because the NLA service is a demand-start service and it is used by several critical system components, including Winlogon.exe.If this service is stopped, the change-requests of the services that are using NLA for network change notifications are cancelled. These services immediately try to reestablish the change requests, thereby demand-starting the service again almost instantaneously. NLA correctly reports to the Service Control Manager (SCM) thread, which requested the stop, that the service stopped successfully; however, Winlogon.exe or another service immediately restarts before you are able to verify the status in the Services snap-in.

Available on: Windows Server 2003, Standard Edition; Windows Server 2003, Enterprise Edition; Windows Server 2003, Datacenter Edition and Windows Server 2003, Web Edition.
