问题
I am trying to check computer group membership through Powershell. I want to be able to specify a certain computer name and find which groups that computer is in but from a Powershell script. I am planning on running the script on a computer, grabbing the hostname, and then printing out what AD groups that computer is in. Is there an easy way to do this?
EDIT: So the plan here is to have a computer check to see what groups it is in, then assign a printer based on which group it is in. We have many printers that only 3 to 4 people use but due to the spread out nature of the users cannot downsize the amount of printers. I was looking at group policy but did not want to create 20 different GPOs. I wanted to do this with a logon/startup script. I'm not sure if this is doable or feasible.
Edit #2: This edit it really late to the party but I figured if anyone found this it could help. We ended up using item level targeting on User>Preferences>Control Panel>Printers objects. We made an account in AD for each group of users needing access to the printers. This worked although it did create a long logon process for the first logon of the computer. We also enabled Point-to-Print restrictions so the drivers were loaded from the servers quietly.
回答1:
This will give you the group membership (group names) of the local computer (requires powershell 2.0):
([adsisearcher]"(&(objectCategory=computer)(cn=$env:COMPUTERNAME))").FindOne().Properties.memberof -replace '^CN=([^,]+).+$','$1'

Apologies if I'm a bit late to the party on this but I needed to find a computer's group membership as well. After a lot of trial and error, this worked for me.
Get-ADComputer "mycomp" -Properties MemberOf | %{if ($_.MemberOf -like "*group name*") {Write-Host "found"} }
I noticed that if the string comparison is on a separate line, I needed to do the following
$g=Get-ADGroupMember -Identity "CN=myADgroup,OU=myOU,DC=corp,DC=com" -server corp.com
foreach($mbr in $g) {if($name.MemberOf -like "*mycomp*" -eq $true) {Write-Host "found"}}
Not sure but I imagine that testing the computer might be faster and easier than testing the group depending on the number of members.

the gpresult method seems to be the only way I can find that is accurate. Querying AD is not accurate since the computer may have been added to groups but not rebooted. I am sure someone could condense this but it worked well enough for what I needed to see.
# Get all active domain servers
$staledate = (Get-Date).AddDays(-90)
$computers = Get-ADComputer -Filter {(OperatingSystem -Like "*Server*") -and (Enabled -eq $True) -and (LastLogonDate -ge $staledate) -and (Modified -ge $staledate) -and (PasswordLastSet -ge $staledate) -and (whenChanged -ge $staledate) -and (Name -notlike "PHXVSSA101A")} | Select name -expandproperty name
$computers = $computers | Where {(Resolve-DNSName $_.name -ea 0) -and (Test-Connection -ComputerName $_.Name -Count 1 -ea 0)} | Sort
# Loop through all active domain servers
Foreach ($computer in $computers)
{
# Pull the gpresult for the current server
$Lines = gpresult /s $computer /v /SCOPE COMPUTER
# Initialize arrays
$cgroups = @()
$dgroups = @()
# Out equals false by default
$Out = $False
# Define start and end lines for the section we want
$start = "The computer is a part of the following security groups"
$end = "Resultant Set Of Policies for Computer"
# Loop through the gpresult output looking for the computer security group section
ForEach ($Line In $Lines)
{
If ($Line -match $start) {$Out = $True}
If ($Out -eq $True) {$cgroups += $Line}
If ($Line -match $end) {Break}
}
# Loop through all the gathered groups and check for Active Directory groups
ForEach ($group in $cgroups)
{
Try {
$check = Get-ADgroup $group -ErrorAction Stop
If ($check) {
$dgroups += $group
}
}
Catch {}
}
# Output server name and any Active Directory groups it is in
$computer
$dgroups
# End of computers loop
}

Heres an LDAP query to find if a computer is in a group recursively:
(((objectClass=computer)(sAMAccountName=COMPUTERNAME$))(memberof:1.2.840.113556.1.4.1941:=DistinguishedNameOfGroup))

回答5:
try running gpresult /V and check under "security GROUPS"
You can also try gpresult /scope computer /v under a command prompt (elevated to admin) for more specific results
