Hi guys !

I would like to get a list of IPs or Host names of all PCs in a domain. I found this API Call which I think can do the task (VB):

#Private Declare Function DsListServersForDomainInSite Lib "ntdsapi.dll" (ByVal hDS As Long, ByVal Domain As String, ByVal site As String, ByRef ppServers As PDS_NAME_RESULTA) As Long


How could this be converted into VDS code:

LOADLIB ntdsapi.dll

%A = @LIB("ntdsapi.dll", DsListServersForDomainInSite, <ret_val type>, args… )
FREELIB ntdsapi.dll

Here is more info on the api:

It looks like you need to use a function DSBind before you can use the dslistservsersfordomainsite function.

Thanks for the info.

However I am not wether servers will include all PCs on a Microsoft Network. I appears that servers are only Windows 2000 and Windows 2003 or ?

Basically I am trying to do what this C function does
It should return a string of the form COMPUTERNAME1|COMPUTERNAME2|...

I found the function on the net somewhere and modified it somewhat but since I am that fluent in C anymore, I guess it will not compile - However I think you'd get the picture anyway.

Here goes:

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>

// Find the servers in a domain
char* ScanDomain( char* userdomain )
{
char *returnstring;

char domname[200];

if (userdomain != NULL)
{
strncpy(domname, userdomain, 200);

TCHAR szDomain[32];
//GetWindowText(wndDomain, domname, sizeof(szDomain));

NETRESOURCE netres;
netres.dwScope = RESOURCE_GLOBALNET;
netres.dwDisplayType = RESOURCEDISPLAYTYPE_DOMAIN;
netres.dwUsage = RESOURCEUSAGE_CONTAINER;
netres.lpRemoteName = domname;
netres.lpProvider = NULL;

HANDLE henum;
DWORD res =
WNetOpenEnum(
RESOURCE_GLOBALNET,
RESOURCETYPE_ANY,
RESOURCEUSAGE_CONTAINER,
&netres,
&henum);
if (res == NO_ERROR) {
printf("Yay!\n");
} else {
return;
}

unsigned char bigbuf[16 * 1024];
DWORD things;
do {
things = 1;
DWORD bufsize = sizeof(bigbuf);
DWORD res = WNetEnumResource(
henum,
&things,
(LPVOID) bigbuf,
&bufsize);
if (res != NO_ERROR) {
break;
}
printf("Found a thing!\n");
NETRESOURCE *found = (NETRESOURCE *) bigbuf;
printf("Item:%s\n", found->lpRemoteName);

// Now take off the double backslash on the beginnig.
char buf [200];
strncpy(buf, & (found->lpRemoteName[2]), sizeof(buf));

// Add to window
//SendMessage(targetwnd, LB_ADDSTRING,0, (LPARAM) buf);

// Add to return string
returnstring+= buf + "|";

} while (things>0);
WNetCloseEnum(henum);

return returnstring;
} else {
return NULL;
}

}



Maybe some more knowledgable in C would like to take a look also ?

Hi henrywood,

You do realize that the C code you posted prints to STDOUT, meaing that it
needs to be run ina dos box.

Let me tinker with this.

[henrywood]

Hi guys!

Yes I am aware - I guess I forgot to remove that line

Bill, just tinker away

Are you gonna wrap it into a DLL (would be very nice!)

A note though: Since I do not currently have a LAN setup at home I would not be able to test it before getting back to work on Tuesday.
Maybe somebody else are willing to test if it actually works


I would like to use it in conjunction with VDSREG to write to the registry of all PCs in the network

See if this helps you.

[henrywood]

Hi Aslan !

Thank you for the tip !

I would prefer a DLL and I think Bill is working on a DLL ? I always try to avoid running hidden system programs using RUNH as they fail on some systems.

However, I have tested the net view suggested by you and that works OK.
