The following functions are implemented in Ws2.dll, and are intended to be used by applications that install Windows Sockets transport and namespace service providers on a machine. These functions neither affect currently running applications, nor are the changes made by these functions visible to currently running applications.

For all providers, a provider identifier is a GUID, which is generated by the developer of the provider (using the Uuidgen.exe utility) and supplied to Ws2.dll.

Function Description


Removes a service provider from the registry.


Retrieves information about available transport protocols.


Registers a new service provider.
