Pregunta
Usando la API de Windows, ¿cómo puedo obtener una lista de dominios en mi red?
Solución
Necesitará utilizar algunas consultas LDAP
Aquí hay un código que usé en un script anterior (fue retirado de la red en algún lugar y lo dejé en los avisos de derechos de autor)
' 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

Otros consejos
Respondí mi propia pregunta:
Utilizar el NetServerEnum función, pasando por el SV_TYPE_DOMAIN_ENUM
constante para el argumento "tipo de servidor".
En Delphi, el código se ve así:
<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 = $80000000;
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;
