已经有人问过了，你查一查嘛，太浪费分数了。

读不出地址，可能是网卡安装上有问题，或者是驱动没有安装正确等。
ppp Adapter是指拨号网络适配器，相应的PPP Adapter的物理地址，就是他的地址。

请教各位:

以下代码(MSDN中的源代码)编译时会有以下错误:

getid.obj : error LNK2001: unresolved external symbol _Netbios@4
Release/test.exe : fatal error LNK1120: 1 unresolved externals

#include <windows.h>
#include <wincon.h>
#include <stdlib.h>
#include <stdio.h>
#include <time.h>

typedef struct _ASTAT_
{
ADAPTER_STATUS adapt;
NAME_BUFFER NameBuff [30];
}ASTAT, * PASTAT;

ASTAT Adapter;

void main (void)
{
NCB ncb;
UCHAR uRetCode;
char NetName[50];

memset( &ncb, 0, sizeof(ncb) );
ncb.ncb_command = NCBRESET;
ncb.ncb_lana_num = 0;

uRetCode = Netbios( &ncb );
printf( "The NCBRESET return code is: 0x%x \n", uRetCode );

memset( &ncb, 0, sizeof(ncb) );
ncb.ncb_command = NCBASTAT;
ncb.ncb_lana_num = 0;

strcpy( ncb.ncb_callname, "* " );
ncb.ncb_buffer = (char *) &Adapter;
ncb.ncb_length = sizeof(Adapter);

uRetCode = Netbios( &ncb );
printf( "The NCBASTAT return code is: 0x%x \n", uRetCode );
if ( uRetCode == 0 )
{
printf( "The Ethernet Number is: %02x%02x%02x%02x%02x%02x\n",
Adapter.adapt.adapter_address[0],
Adapter.adapt.adapter_address[1],
Adapter.adapt.adapter_address[2],
Adapter.adapt.adapter_address[3],
Adapter.adapt.adapter_address[4],
Adapter.adapt.adapter_address[5] );
}
}
什么原因?如何处理?不胜感激!!!

NetApi32.lib没有加入工程吧。

多谢!
但是为什么在有些机器上读不出(已装网卡)
还有请问PPP Adapter的物理地址是什么意思?
多谢了!

网卡安装正常,可正常连接到局域网上.可就是读不出网卡的ID
我看到msdn中有这样一句话:
The following code does not work reliably on Windows 95 or Windows 98.
它的意思是这种做法在95,98无法保证可靠性.这到底是怎么回事?有没有其它办法?
我用其它工具能读出.
