Hi!
Sorry if this topic comes back again, but the code I have found in msdn and
in google doesn't work for me. I need a list of nt domains, as it is shown
in a combo box after winlogon starts up.
a function GetPolicyHandle was found here
http://msdn.microsoft.com/library/de...us/security/se
curity/opening_a_policy_object_handle.asp
I get no entries in LsaEnumerateTrustedDomains but there is at least one
domain that I can log into
from my computer.

thanks in advance
hs
my function is here
void listDomains ()
{
LSA_HANDLE policy = GetPolicyHandle ();
LSA_ENUMERATION_HANDLE enumh;
ULONG l = 0, i;
NTSTATUS status;
USES_CONVERSION;
PLSA_TRUST_INFORMATION trustInfo = NULL;
WCHAR StringBuffer[256];
WriteLog ("list domains");
if (!policy)
{
WriteLog ("policy NULL!");
return;
}
ZeroMemory (&enumh, sizeof (enumh));
while (1)
{
WriteLog ("enumerate trusted domains...");
status = LsaEnumerateTrustedDomains (policy, &enumh, (PVOID*) &trustInfo,
32000, &l);
if (status == STATUS_NO_MORE_ENTRIES)
{
WriteLog ("no more entries");
break;
}
WriteLog ("found %d entries", l);
for (i=0; i<l; i++)
if( trustInfo[i].Name.Length < 256 )
{
wcsncpy(StringBuffer,
trustInfo[i].Name.Buffer,
trustInfo[i].Name.Length
);
StringBuffer[trustInfo[i].Name.Length] = (WCHAR) NULL;
WriteLog("%d %s", i, W2T (StringBuffer));
}
}
LsaFreeMemory (trustInfo);
if (status == STATUS_SUCCESS)
break;
}
}
