NetWkstaGetInfo() Question

[RobJones]

Hello, I am using the following to pull the domain/workgroup name of a remote computer. This works just fine when I use the remote computers IP address but if I use the machine name it fails with an access is denied error. Has anyone experienced the same problem or does anyone have any ideas why this is happening?

DWORD dwLevel = 100;
LPWKSTA\_INFO\_100 pBuf = NULL;
NET\_API\_STATUS nStatus;

nStatus = NetWkstaGetInfo(L"\\\\\\\\192.168.1.2", dwLevel, (LPBYTE \*)&pBuf);

if (nStatus == NERR\_Success)
{
	TRACE(L"Name:\\t\\t%s\\n",		pBuf->wki100\_computername);
	TRACE("Platform:\\t%d\\n",	pBuf->wki100\_platform\_id);
	TRACE(L"Domain:\\t\\t%s\\n",	pBuf->wki100\_langroup);
}
else
{
	char error\[1024\];
	FormatMessage(FORMAT\_MESSAGE\_FROM\_SYSTEM, NULL, nStatus, NULL, error, sizeof(error), NULL);
	TRACE("Error: %s", error);
}

// Free the allocated memory.
if (pBuf != NULL)
	NetApiBufferFree(pBuf);

Thanks, Rob Whoever said nothing's impossible never tried slamming a revolving door!

Your code snippet works fine for me using either an IP address or a machine name. How are you specifying the machine name?

I specify it like.... L"\\\\machine". I'm going to test it at work today on a few other machines. Just thought it was weird that simply switching between IP and machine name would cause that error. Whoever said nothing's impossible never tried slamming a revolving door!

Makes me wonder if it's a name-resolution issue. Do you have a problem using gethostbyname()? In other words, can you use this function to resolve a host name to its IP address?
