WNetUseConnection Error

Hey there,

I am using this function "WNetUseConnection" , it's working fine on many systems, but when I am using it on win2k3 R2 I am getting 1213 error which is "the network could not be reached"..
Here is the snippet of parameters I am passing to this function, I hope someone can point me out to fix this error..

p.s: rc is returning 1213, it returns 0 ERROR_SUCCESS on other systems
thanks

TCHAR szRemoteResource[_MAX_PATH];
   TCHAR  szAccessName[0x100];
   DWORD rc,dwResult,dwBuffSize=0x100;
_snprintf( szRemoteResource,sizeof(szRemoteResource), ("\\\\%s\\%s"), "192.168.16.16", "IPC$");   
   NETRESOURCE nr;
      nr.dwType = RESOURCETYPE_ANY;
      nr.lpLocalName = NULL;
      nr.lpRemoteName = (LPTSTR)&szRemoteResource;
      nr.lpProvider = NULL;
rc=WNetUseConnection(GetForegroundWindow (),&nr, "",
		                                           "", CONNECT_INTERACTIVE,
		  szAccessName,&dwBuffSize,&dwResult);

According to the MSDN 1213 is...

ERROR_INVALID_SERVICENAME
1213 (0x4BD)
The format of the specified service name is invalid.

Have you tried calleding WNetGetLastError()?

The WNetGetLastError function retrieves the most recent extended error code set by a WNet function. The network provider reported this error code; it will not generally be one of the errors included in the SDK header file WinError.h.

What happens if you try to manually access this resource from the machine using "net use"?

I rechecked, the error was 1231 which is ERROR_NETWORK_NOTFOUND , I will use WNetGetLastError() and update this post..

Can anyone help ?
Thanks

Oops, I transposed the 1 and the 3 :) My bad -- doh! <--- slaps himself *hard*

Let me repost just to clear up the confusion I might have created

>> Can anyone help ?
Did you try what I suggested above?

Also, have you tried to ping the end-point from that machine to see if it can actually see it?

yeah, I agree, since the code works on different platforms but do you think it's possible to fix that problem ?

>> but do you think it's possible to fix that problem ?
From a code point if view, there is nothing to fix. From a windows networking point of view that is a new question that needs to be asked in a windows networking zone.
