Speed up query

I'm currently looking for the fastest way to:
1) scan all computers in domain
2) connect to the computers and look to see who is part of the local administrators group
3) expand local and domain groups if they are members of the local administrators group

There is a powershell script here by chris_dent that seems to be working so far, but it's been a few hours and it's only done 40 computers...
http://www.experts-exchange.com/Programming/Languages/Visual_Basic/VB_Script/Q_23969323.html
I'd like to do what the script does, but perhaps split up the load... gather a list of all the computers, split that list into multiples of 10 let's say... computers 1-10, computers 11-21 etc... and maybe launch 4 or more seperate process's to take on those lists... process 1 takes computers 1-10 process 2 takes computers 11-21 etc...

If it could be done faster in vbs/wmi I'm down for that too ;)

Oh, and I'm not sure yet, as the current script I have hasn't finished, but it could probably go faster if all domain groups and their members were enumerated once, it looks like they are being looked up each time they are present on a computer, at least from the wireshark sniffing I have going to watch the progress.
If I knew how to script, I'd write it to:
look up all computers in the domain
  create list of computers in arrays of 10
    look up all groups and the members in the domain
      start separate process, 0-4 (max 8) working on the arrays of 10
       connect to all computers in the domain
         look at who is in the local admin group of the computers
That might not be a good way, I don't know, thought I'd put it out there ;) Programatically, I have no idea how that would be done via vbs/wmi and or powershell.

what do you mean :

expand local and domain groups if they are members of the local administrators group

do you want all computers include servers ?

Chris DentPowerShell DeveloperCommented:

Multi-threading, I can see the reasoning, I've used it successfully in the past for big WMI queries. Although with VbScript it's nothing more complex than maintaining a set of separate scripts and a launcher.

Would you consider moving up to a more powerful language? Rather tempted to suggest C#.

Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

 
Rich RumbleSecurity SamuraiAuthor Commented:
I'm not opposed to using separate scripts, or even files. I'd think it might be easier to use two different files, like saving all the computer names (servers, pc's etc..) to one file, and then also saving domain groups and their members to another file. Then connect to each computer in the domain, have a look at who is in the local admin group, then use the file that contains any domain groups that may be listed, and naturally look up members of local groups if any.
This may also aid in the ease of creating the multi-threading. Also writing to seperate files can give flexibility in what language is then used to parse these files and do the matching. I'm not opposed to other languages like C#, whatever would be useful for anyone looking to do the same thing, and whatever the expert is comfortable with.

I've looked at this script, but it doesn't seem to work for me even as a test. I changed the ldap query to what has worked for me in the past, but no joy
http://www.microsoft.com/technet/scriptcenter/scripts/templates/default.mspx?mfr=true
Output:
 could not be reached.
 could not be reached.
 could not be reached.
 could not be reached.
etc... Never sends the actual pings...
This one will get the list of the computers, but not connect to them...
http://www.microsoft.com/technet/scriptcenter/scripts/templates/default.mspx?mfr=true
I've inserted various other scripts between the "insert your code -- end portions, with no more success. I can see from wireshark that the list of pcs is being pulled, but not acted on after that.

They only use Name to connect, if you didn't have a DNS suffix for the domain on your PC it would fail. I prefer to use dnsHostName, removes at least one bit of ambiguity.

Rich RumbleSecurity SamuraiAuthor Commented:
That was true(dns suffix missing), but still same things... no actual icmp being sent, not trying to connect to machines...

So what do you think... it looks like one can dump a list of computers (servers and all) fairly quickly, and I'd assume you could look up domain groups and their members pretty fast as well. What about then breaking up the list of computers into a few process's, that ping and attempt to connect and look for who is listed in the local admins...

Rich RumbleSecurity SamuraiAuthor Commented:
Ok, spent all day mangling and "frankinstein'ing" this code together, but so far so good...
It pings, it connects and let's me know who is in the local admin group, but it doesn't recursively look up groups and their members... I was hoping not to settle for that...
Improvements needed, and very welcome if anyone has any idea's. It is faster as far as I can tell, or at least I get instant results, than the powershell script.
Change the Ldap strings to suit for testing (line 13)
Oh and I know it's ugly ;)

C:\Sandbox\admin-lookup.vbs(8, 3) Microsoft VBScript runtime error: Variable is undefined: 'objGroup'
That was the origianal error, it would echo the computer name an OS, then give that error and exit.

And, can a count of the total 'computers' retrieved, that are going to be attempted be echoed to the top, so it's easier to make sure it tired them all... I changed the script to csv output as well.

Also, ahem, I was able to make the script work, on error resume next, removed "Option Explicit"
However I'd like to not have to force it, rather have the corrections made if possible ;)
So far so good! I think it is almost done, it would still be nice to launch some more process's to speed up further, but I may put that to another question.

Oops. Just needed Dim objGroup adding as below. Fixed here.

I popped in basic error handling for the GetMembers subroutine as well. I figure there's a chance it might fail to connect even if the system responds to Ping.

Thanks, the admins aren't populating :( The script I *hacked* was working in that regard. When the hacked version was working, it was throwing out WinNT://domain/username ... can the winnt:// be trimmed, and can a "count" of the total computers be echo'd at the beginning?
thanks again!

Sorry, I missed another Dim out.

Trimmed off the WinNT:// part and added an echo of the Record Count before it starts looping through.

That is working well! Does it make sense (speed wise) to look up all domain groups and break down their members (if not empty) perhaps before running a script like the above, so that this script can then look to that file to do the domain group break downs, instead of having to keep looking up "domain admins", "backup operators" etc... I can make that a separate question if you think it's warranted. You'd still have to look at the computers themselves for local groups and members...

Chris DentPowerShell DeveloperCommented:

It depends how big the domain is I guess :)

If the domain is small, it does make sense because you're not thinking about a lot of data.

Doing that is extremely questionable in larger domains. I'd drop back to my original script, removing the focus on Administrators and simply enumerating the local groups on the system. Although the search would be a bit more focused than just all computers in the domain.

Rich RumbleSecurity SamuraiAuthor Commented:
Ok, last thing, I promise for this one ;) Can it toggle the break-down on/off via command line.. can I list the just the admin users, no break down of group members, or run the script and use a /bdg or something to break down the group users?
I asked something similar for a different script here:
http://www.experts-exchange.com/Programming/Languages/Visual_Basic/VB_Script/Q_23546376.html
I am going to open another Q in a few...

Sure, we can just add a flag in to say whether or not to use recursion. With this it simply echoes the group as a member rather than trying to get membership from there.

Or via the command line. Lets just have it look for a "-r" in the command, although it can be anything really.

That is perfect... I could keep you busy for weeks writing stuff like this...
I've just posted another question here:
http://www.experts-exchange.com/Programming/Languages/Visual_Basic/VB_Script/Q_24137674.html
I have 1000+ computers in several domains, 90% are pingable, so it's quite slow still even without recursion, let's explore ways to speed it up more!
