Thank you . I download the demo, but it does not work too. we all use Windows SP2 system. Now i have found a way to achieve my purpose. i send ARP request to all Local ip addresses. the ones who reply my request exit in my LAN.

Thank you for your reply. The problem is that not every hosts have the ablity to enume hosts in LAN by using WNet functions. only the one which is a domain administrator have the ability. so i think the WNet functions do not fit me.

now I have succefully enumed hosts of my LAN by sending ARP request. but this require to install Ourself protocol driver to send ARP requests(SendARP does not fit). It worked very good.

my demo code is here(using WNet). it can not enume hosts: #include "../common/initsock.h" //#include "Ws2tcpip.h" #include #include #include #include #include CInitSock theSock; // to call WSAStartup function using namespace std; #include "Iphlpapi.h" #pragma comment(lib, "Iphlpapi.lib") #pragma comment(lib, "Mpr.lib") BOOL EnumRes(); void main() { EnumRes(); } BOOL EnumRes() { HANDLE hEnum; DWORD dw = ::WNetOpenEnum(RESOURCE_GLOBALNET, RESOURCETYPE_ANY, 0, NULL, &hEnum); if(dw != NO_ERROR) { printf(" OpenEnum failed \n"); } DWORD cCount = -1; u_char lpBuffer[1024*16]; DWORD cBufferSize = 1024*16; do { dw = ::WNetEnumResource(hEnum, &cCount, lpBuffer, &cBufferSize); NETRESOURCE *pRes = (NETRESOURCE *)lpBuffer; if(dw == NO_ERROR) { for(int i=0; i
