回答了我自己的问题：

使用NetServerEnum函数，为" servertype"参数传入SV_TYPE_DOMAIN_ENUM常量。

在Delphi中，代码如下所示：

<snip>
type
  NET_API_STATUS = DWORD;
  PSERVER_INFO_100 = ^SERVER_INFO_100;
  SERVER_INFO_100 = packed record
    sv100_platform_id : DWORD;
    sv100_name        : PWideChar;
end;

function NetServerEnum(  //get a list of pcs on the network (same as DOS cmd "net view")
  const servername    : PWideChar;
  const level         : DWORD;
  const bufptr        : Pointer;
  const prefmaxlen    : DWORD;
  const entriesread   : PDWORD;
  const totalentries  : PDWORD;
  const servertype    : DWORD;
  const domain        : PWideChar;
  const resume_handle : PDWORD
) : NET_API_STATUS; stdcall; external 'netapi32.dll';

function NetApiBufferFree(  //memory mgmt routine
  const Buffer : Pointer
) : NET_API_STATUS; stdcall; external 'netapi32.dll';

const
  MAX_PREFERRED_LENGTH = DWORD(-1);
  NERR_Success = 0;
  SV_TYPE_ALL  = $FFFFFFFF;
  SV_TYPE_DOMAIN_ENUM = 000000;

function TNetwork.ComputersInDomain: TStringList;
var
  pBuffer        : PSERVER_INFO_100;
  pWork          : PSERVER_INFO_100;
  dwEntriesRead  : DWORD;
  dwTotalEntries : DWORD;
  i              : integer;
  dwResult       : NET_API_STATUS;
begin
  Result := TStringList.Create;
  Result.Clear;

  dwResult := NetServerEnum(nil,100,@pBuffer,MAX_PREFERRED_LENGTH,
                            @dwEntriesRead,@dwTotalEntries,SV_TYPE_DOMAIN_ENUM,
                            PWideChar(FDomainName),nil);

  if dwResult = NERR_SUCCESS then begin
    try
      pWork := pBuffer;
      for i := 1 to dwEntriesRead do begin
        Result.Add(pWork.sv100_name);
        inc(pWork);
      end;  //for i
    finally
      NetApiBufferFree(pBuffer);
    end;  //try-finally
  end  //if no error
  else begin
    raise Exception.Create('Error while retrieving computer list from domain ' +
                           FDomainName + #13#10 +
                           SysErrorMessage(dwResult));
  end;
end;

我们将需要使用一些LDAP查询

这是我在以前的脚本中使用过的一些代码(它是从网上某个地方摘下来的，我已经在版权声明中留下了)

' This VBScript code gets the list of the domains contained in the 
' forest that the user running the script is logged into

set objRootDSE = GetObject("LDAP://RootDSE")
strADsPath =  "<GC://" & objRootDSE.Get("rootDomainNamingContext") & ">;"
strFilter  = "(objectcategory=domainDNS);"
strAttrs   = "name;"
strScope   = "SubTree"

set objConn = CreateObject("ADODB.Connection")
objConn.Provider = "ADsDSOObject"
objConn.Open "Active Directory Provider"
set objRS = objConn.Execute(strADsPath & strFilter & strAttrs & strScope)
objRS.MoveFirst
while Not objRS.EOF
    Wscript.Echo objRS.Fields(0).Value
    objRS.MoveNext
wend
