Hi all,

I've wrote a sort of Big Brother script, the scripts allows and denies Operating Systems on our Domain and more of that stuff....

Now I've got a problem, The users have to log on a domain, I want to check if that user has local admin rights, and I want to check if the Domain Administrator is in the local group Administrators...

Is this possible wilth NET or KIX? Help me! [Smile]

You could review List and delete members of local admin group on remote PC's and during logon or Is user part of admnistrators group .

You have to be concerned with the users permissions on the client. If they are not adminstrator, I do not believe that they will be able to enmuerate the local adminstrators group.

Look...

I want to check with kix the following:

For example our domain is DOM,

I want to check if DOM\Administrator is in de local administrator group on that computer... If NOT then ADD... I think this is very hard to script [Smile]

My second target is:

For example we've got user BLA

DOM\Bla may have local administrator rights... but Bla may have NOT local administrator rights. If he has.. then DELETE and Logoff(1)

It's hard to explain you know, I'm a dutch man (I bet I'd get no more replies from of now [Wink] )

Praetorian,
Howard gave you a couple of very good leads to get you started. If you get no more replies, it is not because you're a Dutchman. Simply restating your objective will not likely help your cause. There needs to be some progression.

Ok. To make changes to the local Administrators group, the person making the change has to have Administrator permissions.

That means:
1) If the user is in the Administrators group, you can easily add the Dom\Administrator account and remove the user account in a Kixtart logon script (as the user). there are code samples in the links I mentioned previously that will get you very close to what you need. In the script I provide in one of the links you simply need to add "$group.Remove(@UserID)" to remove the user account.

2) If the user is not an Administrator, the logon script will not work for you at all unless you can use SU.exe or Runas.exe. In this case, you will ether need to have another DOM\account that has Admin permissions or use the local adminstrator account. If you have access via a Domain account you can use ADSI to target the remote computer or use a Perl Compiled utility AddToAdmin.exe from my Perl Utilities Web Page.

If you give the coding a shot, many of will review and point you in right direction. No one likes to write solution for others without compensation but we do like to assist.

Hi Dutchie

Might try the low-tech approach, not sure if perms will get in the way though ... this might be a piece of the puzzle:

BREAK ON

$LOCALGROUP = "ADMINISTRATORS"
$GLOBALGROUP = "DOM\ADMINISTRATOR"

SHELL '%COMSPEC% /C NET LOCALGROUP "$LOCALGROUP" | FIND /I "$GLOBALGROUP" >NUL 2>NUL'

IF @ERROR = 0
 ?"$GLOBALGROUP IS A MEMBER OF LOCAL $LOCALGROUP"
ELSE
 ?"$GLOBALGROUP IS NOT A MEMBER OF LOCAL $LOCALGROUP"
ENDIF

EXIT

Congratulations on #1000 Howard! [Smile]

As to the current issue at hand... I always liked the Jens way of doing things via task scheduler... This allows you to execute tasks with administrator privilege even though the logged on user does not have admin privileges.

not net commands uttleast can do that...

so new interface could do that and with rcmd.
actually, at is the saver here.

copy that script with appropiate usernames to that machine,
schedule a job on that target with that script and delete after execution that script.

cheers,

Was thinking that this would be a job for any old NT5 workstation, ADSI and the WinNT provider, for example, to enumerate remote objects in the local administrators group on a workstation:

break on

$WKSTA = "xxxyyy" ; the target machine
$ADMINID = "john.doe" ; local or domain\account
$ADMINPWD = "password" ; password
$LOCALGROUP = "administrators" ; the local group on target machine

$root = getobject("WinNT:")

$group = $root.opendsobject("WinNT://$WKSTA/$LOCALGROUP","$ADMINID","$ADMINPWD",0)

for each $object in $group.members
 ? $object.adspath
next

exit 1


Haven't been able to successfull enumerate GLOBAL DOMAIN GROUPS in there yet ... anyone ?

Hello again!

With your help my scripting project is on scheme... But I've got 1 little problem... See my code:

code:
? "Checking availability of Domain Administrator account..."
SHELL '%COMSPEC% /C NET LOCALGROUP "Administrators" | FIND /I "RPZ\DomainAdministrator" >NUL 2>NUL'
IF @ERROR = 0
? "Error: RPZ\DomainAdministrator account not available!"
logoff(1)
ELSE
? "Everything okay!"
ENDIF
This code is running on the workstations from the netlogon directory on the domain controller... It looks like the checking with the SHELL command is not happening on the workstation, but on the domaincontroller hisselve!

This because my workstation has the user RPZ\DomainAdministrator.., and the script IS running! but however... my script is telling me, that user is nog available... [Confused]

If you run that script it won't work because:

"domainadministrator" is not a valid account. On my Windows 2000 machine in my domain, you use:

code:
SHELL '%COMSPEC% /C NET LOCALGROUP "Administrators" | FIND /I "RPZ\Domain Admins" >NUL 2>NUL'
instead of the line you have. If you go to a command prompt on the target machine and check by typing:

NET LOCALGROUP "Administrators"

If the domain admins group is listed, it will tell you what you need to look for.

Personally, I like the ADSI method much better for doing this. (See posts above.)

ADSI is not the way for me..

If you read my post.. you readed that the script DO work... the only problem is that de SHELL command is executed on the domain controller..

Can somebody tell me how to run the shell command on the workstation?

Every workstation here runs the script from the netlogon dir at the domain controller...

praetorian, the shell is run everywhere...

if the %comspec% is set to DC location it's run there.

check it for the user.

Logon scripts run on the client unless as Lonkero said, the %comspec% points to the DC.

As I understand it:

Summary:

1. you need to check the client to see if the currently logged on user has local admin rights.

1a. If user doesn't have local admin rights, log them off immediately.

2. You need to check the client to see if the domain administrator has local admin rights.

2a. If domain admin doesn't have local admin rights, add them to local admin group.

------
Comments:

1. As far as I know, domain administrators are granted local admin rights to NT/2000/XP workstations by default. There may be rare exceptions, but for the most part this should hold true.

2. Before coming back to the domain admin question, all you need to do is check to see if the current user is in the local admins group and log them off if they aren't. This is not too difficult.

3. Assuming you check to see if the user is a local admin (as in #2), then you know that they are and you can verify that domain admins are local admins as well, using a similar method to #2.

4. Logon scripts run on the client PCs, not on the server they are being accessed from, except in very RARE cases. Otherwise, drive mappings, setup programs, etc would go to the server instead of the client.
