Get Mac-address with NETBIOS

I'm searching for an unique identification for a machine, so I considered the mac-address.
I used the NEETBIOS function, by calling the command NCBASTAT, to get the mac-address. However, this works only if there is a connection to the network. Is there an alternative way to get the mac-address.
Or are there any unique alternative machine identifiers ?

Search for other threads, one of the latest had a program which gets the MAC Address.

Setting the MAC Address as a unique identifier is not simple. My colleague always used this mechanism to identify a machine. But nowadays you have more than one network adapter in a machine (LAN, WLAN, ISDN, Modems...) and that was (or is) a problem for him.

If your intention is to prevent pirate copyingof your software, then the general concensus (that I have seen)is that a "home grown" solution will not be good enough. It may deter a casual user but not adetermined effort.

If that is not the problem then, if you tell us what you want to achieve, maybe someone here will be able to help.

It's a part of a software access. So I think for the purpose of our software, the pirate copy protection is sufficient.
The mac-address, machine identification (for licence checking)is not the main goal. Moreover it is to identify, the machine or data of a specific machine.

The Windows system identification number (SID) and program identification number (PID)are useful when trying to uniquely identify a Windows machine.Here's some C++ code to get these numbers. Error handling and conversion to Fortran is left as an exercise for the reader... :)

[cpp]#include 
#include 
#include 
#include 
#include 

void id()
{
    // Get the PID (Product Id) string from the registry
    const TCHAR kSubKey[] = _T("SOFTWAREMICROSOFTWindows NTCurrentVersion");
    const TCHAR kValueName[] = _T("DigitalProductId");
    HKEY hKey = NULL;
    if( RegOpenKeyEx(HKEY_LOCAL_MACHINE, kSubKey, 0, KEY_QUERY_VALUE|KEY_WOW64_64KEY, &hKey) == ERROR_SUCCESS )
    {
        DWORD dwType;
        if( RegQueryValueEx(hKey, kValueName, NULL, &dwType, NULL, NULL) == ERROR_SUCCESS )
        {
            if( dwType&(REG_SZ|REG_EXPAND_SZ))
            {
                char sPidStr[1024] = {0};
                DWORD dwSize = sizeof(sPidStr);

                {

Here is Fortran version without error checks.

[cpp]PROGRAM pid_main
USE ifwin
IMPLICIT NONE
CHARACTER(*), PARAMETER :: kSubKey    = "SOFTWAREMICROSOFTWindows NTCurrentVersion"C
CHARACTER(*), PARAMETER :: kValueName = "DigitalProductId"C  
INTEGER (HANDLE) :: hKey = NULL  
INTEGER (BOOL) :: iret
INTEGER (DWORD):: dwType, dwSize = 1025 
CHARACTER (1025) :: sPidStr = ''  
INTEGER :: nlen
iret = RegOpenKeyEx(HKEY_LOCAL_MACHINE, kSubKey, 0, IOR(KEY_QUERY_VALUE, KEY_WOW64_64KEY), LOC(hKey) )
iret = RegQueryValueEx(hKey, kValueName, NULL, LOC(dwType), NULL, NULL)
IF ( dwType == IOR(REG_SZ, REG_EXPAND_SZ) ) THEN  
 iret = RegQueryValueEx( hKey, kValueName, NULL, NULL, LOC(sPidStr), LOC(dwSize) )  
 nlen = INDEX( sPidStr(9:), ACHAR(0) ) - 1
 PRINT *, 'PID=', sPidStr(9:nlen + 8) 
ELSE
 STOP 'Error: RegQueryValueEx'
END IF   
STOP
END PROGRAM pid_main[/cpp]

[cpp]PROGRAM sid_main
USE, INTRINSIC :: ISO_C_BINDING
USE ifwin
IMPLICIT NONE

CHARACTER (LEN = 2048) :: Domain=''
INTEGER (BOOL) :: iret
INTEGER (PVOID) :: pSid
INTEGER (LONG) ::  DomainLen, SidLen = 0
CHARACTER (256):: SidStr
INTEGER (LPLONG) :: psidstr
POINTER (pSidStr, SidStr)
INTEGER (ENUM) :: AccountType  
INTEGER :: nlen
!
iret = GetComputerName( ComputerName, LOC(ComputerNameLen) ) 
!PRINT *, 'ComputerName =', ComputerName(1:ComputerNameLen)
iret = LookupAccountName(NULL, ComputerName, NULL, LOC(SidLen), Domain, LOC(DomainLen), LOC(AccountType) )

!
nlen = INDEX(SidStr, ACHAR(0)) - 1
PRINT *, 'SID=', SidStr(1:nlen) 
iret = LocalFree(pSidStr)
iret = GlobalFree(psid)
STOP
END PROGRAM sid_main[/cpp]

P.S. In the MacAddress code (http://software.intel.com/en-us/forums/showthread.php?t=62485), please replace the DO LOOP as below. The DO LOOP index, which should be i, was 1.
[cpp]DO i = 1, 16   
! PRINT *, AdapterInfo(i)%pNext   
! PRINT *, AdapterInfo(i)%ComboIndex   
! PRINT *, AdapterInfo(i)%AddressLength   
 PRINT '(A)', AdapterInfo(i)%Description(1:INDEX(AdapterInfo(i)%Description(1:128), CHAR(0)))   
 PRINT '(5(Z2.2,"-"), Z2.2)', AdapterInfo(i)%Address(1:AdapterInfo(i)%AddressLength)   
 PRINT '(8A)', AdapterInfo(i)%IpAddressList%IpAddress, AdapterInfo(i)%IpAddressList%IpMask  
 IF (AdapterInfo(i)%pNext == NULL) EXIT   
END DO
