请问在Windows2000下如何获得网卡地址（6字节的MAC地址）

[cchuocp]

如题。

将NCB.NCB_CallNmae设置为"*"，然后调用NCBSTAT命令就可以了

[slyfox]

ipconfig /all

#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];

int i;

memset( &Ncb, 0, sizeof(Ncb) );
Ncb.ncb_command = NCBENUM;
Ncb.ncb_buffer = (UCHAR *)&lenum;
Ncb.ncb_length = sizeof(lenum);
uRetCode = Netbios( &Ncb );
printf( "The NCBENUM return code is: 0x%x \n", uRetCode );

for(i=0; i < lenum.length ;i++)
{
memset( &Ncb, 0, sizeof(Ncb) );
Ncb.ncb_command = NCBRESET;
Ncb.ncb_lana_num = lenum.lana[i];

uRetCode = Netbios( &Ncb );
printf( "The NCBRESET on LANA %d return code is: 0x%x \n",
lenum.lana[i], uRetCode );

memset( &Ncb, 0, sizeof (Ncb) );
Ncb.ncb_command = NCBASTAT;
Ncb.ncb_lana_num = lenum.lana[i];

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

uRetCode = Netbios( &Ncb );
printf( "The NCBASTAT on LANA %d return code is: 0x%x \n",
lenum.lana[i], uRetCode );
if ( uRetCode == 0 )
{
printf( "The Ethernet Number on LANA %d is:
%02x%02x%02x%02x%02x%02x\n",
lenum.lana[i],
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] );
}
}

}

为什么要强调是Win2000？
这些方法都是通用的。

leonfu(子夜星光) 的那段程序是经典的方法.很多地方都有.应该可以解决你的问题

[cchuocp]

to NowCan:Windows95下可以利用GUID得到MAC值。
to Others:以前不知道如何给分，所以没有结。另leonfu所给的方法需要安装NetBIOS协议。否则返回的随机值，每次重启动后都会变。

to cchuocp:那有什么方法可以在win2000下，又没有安装netbios协议的情况下获得MAC 地址呢？期待高手回答……
