I got a client who asked me to find all of his Dhcp and DNS servers with some additional info like DC servers and operationsystem
so i decided to try sharpen my powershell skills but im still new to this so i wrote this script but i guess something is still missing because it doesnt work
EDIT: i managed to find a way to get the info i want which is the OS but it gets me back ALL the servers in the company
$servers = get-dhcpserverindc
foreach($server in $Servers){
get-adcomputer -filter {Operatinsytem -like "*windows server*"} -properties
Operatingsystem | sort name | format-table name,Operatinsytem
}
This is not too tricky. First off, you connect to a machine with the RSAT Tools installed, like an admin server, jump box, or Domain Controller, and get a list of all DHCP Servers.
$DHCPServers = Get-DhcpServerInDC
Then we use PowerShell's built in looping logic to step through each server, and check for the OS info you need.
ForEach ($DHCPServer in $DHCPServers){
$OSInfo = Get-CIMInstance -ComputerName $DHCPServer.DnsName -ClassName Win32_OperatingSystem
}
Finally, we'll modify this above to return the info you're looking for, namely the IP Address, Name, and OS Version
ForEach ($DHCPServer in $DHCPServers){
$OSInfo = Get-CIMInstance -ComputerName $DHCPServer.DnsName -ClassName Win32_OperatingSystem
[pscustomobject]#{
ServerName = $DHCPServer.DnsName;
IPAddress=$DHCPServer.IpAddress;
OS=$OSInfo.Caption
}
}
ServerName IPAddress OS

From there, you can store it in a variable, make it a spreadsheet, do whatever you need to do.
Hope this helps.
If this isn't working, make sure you have enabled PowerShell Remoting first.

I need to link a computer to an object in Active Directory.
Basically, I need to link a locally available property to a property that can be found in AD so I can positively link the device to the computer object in Active Directory. The device may be off network, and not able to access a domain controller when it is queried.
From research, the computer's objectGUID or objectSID attributes stored locally do not match the AD ones.
ie:
get-adcomputer -identity ComputerName -property MachineGUID,SID
returns different GUID and SID than the ones found via
wmic path win32_computersystemproduct get uuid
and PSTools's
PSGetSID
..so, is there an indentifier that can be retrieved both locally and in AD that can allow to match a computer?
Thanks
Try locally:
Get-WmiObject -class SoftwareLicensingService | Select-object ClientMachineID
and then on AD Domain controller:
Import-module activedirectory
$ComputerName="enter computername here"
$Computer = Get-ADComputer –Identity $ComputerName –property *
$ComputerCMID = Get-WmiObject –computer $ComputerName -class SoftwareLicensingService | Select-object ClientMachineID
Write-Output "$ComputerName has the CMID: $ComputerCMID "
I already knew how to get all network adaptors names, but I can't tell the difference between normally using and not identified
By using
netsh interface ip show interfaces
or other commands ,you may get all adaptors names.
The necessary information can be obtained using the Win32_NetworkAdapter class.For example:
Get-CimInstance -ClassName Win32_NetworkAdapter -Filter #'
NetConnectionID = "Local Area Connection" AND
NetConnectionStatus=2 AND NetEnabled = True AND PhysicalAdapter = True
'# | Format-List *
The Get-WmiObject cmdlet can also be used, but starting in PowerShell 3.0, it has been superseded by Get-CimInstance.Starting with Windows 8, you can use the Get-NetAdapter cmdlet.
I am trying to create a deployment script which adds freshly deployed workstation primary users to local admin group. I utilized CCM_userAffinity class to obtain username, however - Add-LocalGroupMember does not accept its output.
Ive tried creating task sequence variable to pass into powershell script which adds to group with no success either. Preferably the solution would be integrated within deployment TS, however due to no success i have reverted to ps package deployment.
$computer = "LocalHost"
$namespace = "root\ccm\Policy\Machine"
$query = "ConsoleUser"
$PrimaryUser = Get-WmiObject -class CCM_UserAffinity -computername $computer -namespace $namespace | select-object $query | format-wide
i expected the output from -class CCM_UserAffinity to be accepted by Add-LocalGroupMember, however i get this instead -
Add-LocalGroupMember : Cannot bind parameter 'Member'. Cannot convert the "Microsoft.PowerShell.Commands.Internal.Format.FormatStartData" value of type
"Microsoft.PowerShell.Commands.Internal.Format.FormatStartData" to type "Microsoft.PowerShell.Commands.LocalPrincipal".
As you plan on using the value you retrieve and not displaying it there is no need to use something like "format-wide" which only makes the output human readable and is the reason for your FormatStartData datatype.
You can just use :
$PrimaryUser = (Get-WmiObject -class CCM_UserAffinity -computername $computer -namespace $namespace).ConsoleUser
which returns a string and that is taken by the -Member argument of Add-LocalGroupMember
One thing to keep in mind is that in theory there can be more than one ConsoleUser per machine. So the ConsoleUser might be an Array or not. If you can guarantee that there is always only one user in your environment per machine (at the point where the ts runs) you can just use it as is. Otherwise you would have to specify which user you want to use and I can of course not tell you what a good rule for that for your environment would be.
Also I hope you checked that the WMI class CCM_UserAffinity is already populated at the stage where you want to run this script, I could not tell you if this is the case.
I have windows domain network, i have about 3000 hosts in there. I would like to just check the info which of those hosts having specified technical user account in their local admin groups. I am not that great at power shell, though I know the base things.
I belive that I have to make a list of all hosts across several subnets I have and then run a script that will try to log on those hosts with looking account credentials.
What could be the best solution?
There is a very detailed post on TechNet about listing all computers in domain.
And here's the WMI query part (PowerShell, $aComputerList is a list of computer names):
foreach ($sComputerName in $aComputerList) {
$sUserPattern = 'Win32_UserAccount.Domain="domainname",Name="username"'
$sGroupPattern = 'Win32_Group.Domain="{0}",Name="Administrators"' -f $sComputerName
$oResult = Get-WmiObject -ComputerName $sComputerName -Class Win32_GroupUser | `
Where-Object {
($_.groupcomponent -match $sGroupPattern) -and `
($_.partcomponent -match $sUserPattern)
}
[Bool]$oResult
}
The hard part is that some computers probably won't be reachable (if they're turned off for instance). So you'll need to run your script several times and remove computers from the list as you get responses from them.
I'd like to create a script that will toggle between setting the DNS settings of my wireless card between automatic selection and a particular IP (openDNS).
Can this be done, and if so what should I look in to?
Thanks!
I personally would look at Powershell to do this. I found a post on how to change your ip settings in a one liner.
Get-WmiObject -class win32_networkadapterconfiguration | where-object -filterscript { $_.IPEnabled -eq ‘True’ -and $_.ServiceName -eq ‘E100B’ } | foreach-object -process { $_.EnableStatic(’192.168.1.200′,’255.255.0.0′) }

I would use netsh (google for it)
Thanks for the link back.
