Parameters

[in, optional] Server

A pointer to a constant string that specifies the name of the computer on which to execute this function. If this parameter is NULL, the local computer is used.

[out] EntryCount

A pointer to a DWORD value that returns the number of names returned in the buffer pointed to by the ComputerNames parameter if the function succeeds.
