Constructors

	Name	Description
	AdminProxy()	Initializes a new instance of the AdminProxy class.

Methods

	Name	Description
	Equals(Object)	(Inherited from Object.)
	GetHashCode()	(Inherited from Object.)
	GetRemoteUpdateServerInstance(String, Boolean, Int32)	Connects to the specified remote WSUS server.
	GetType()	(Inherited from Object.)
	GetUpdateServer()	Gets an IUpdateServer object that represents the local WSUS server.
	GetUpdateServer(String, Boolean)	Gets an IUpdateServer that represents a remote WSUS server of the given name.
	GetUpdateServer(String, Boolean, Int32)	Gets an IUpdateServer that represents a remote WSUS server of the given name on the given port.
	GetUpdateServerInstance()	Gets an IUpdateServer object that represents a local WSUS server.
	ToString()	(Inherited from Object.)

Remarks

AdminProxy has both static (shared in Visual Basic) and non-static methods for getting a IUpdateServer. If you use any of the static GetUpdateServer methods to retrieve an interface to the WSUS server, you will not have to instantiate an instance of AdminProxy. However, if you use the non-static GetUpdateServerInstance method, then you must use the new keyword to create an instance of AdminProxy.

Important

This class is not thread safe.

Examples

The following is an example in Visual Basic of the use of one of the static (shared in Visual Basic) methods to get an IUpdateServer representing a local WSUS server.

Dim iUpdateServer as IUpdateServer
iUpdateServer = AdminProxy.GetUpdateServer

The following is an example in Visual Basic of the use of the non-static method to get a IUpdateServer representing a local WSUS server.

Dim iUpdateServer as IUpdateServer
Dim proxy as New AdminProxy
iUpdateServer = AdminProxy.GetUpdateServer
