Get-ServerNames.ps1
Here’s the script I metioned a few days ago. I wrote this a while back (Pre-RC0, I think).
Anyway, if you’ve got a bunch of servers that you need to perform a common task on (copy files, check event logs, etc), this is handy…however, it only works if you’ve got the Managed By field set in AD. Otherwise, you’re SOL. First, it makes sure the account name given exists in AD, then searches AD for and computer objects managed by that account. It uses write-output to return the list of servers. It outputs strings, not objects, since that’s all I needed out of it.
Syntax is: .\get-servernames.ps1 <samaccountname>
$root = new-object DirectoryServices.DirectoryEntry 'LDAP://dc=foo,dc=bar,dc=com'
$searcher = new-object DirectoryServices.DirectorySearcher
$searcher.SearchRoot = $root
$searcher.Filter = "(samaccountname=$($args[0]))"
$results = $searcher.findOne()
if ($results -eq $null) {
write-host -fore 'blue' -back 'white' "`"$($args[0])`" not found"
exit(1)
}
else {
$dn = $results.GetDirectoryEntry().distinguishedname
$searcher.Filter = "(&(samaccounttype=805306369)(managedby=$($dn)))"
$servers = $searcher.FindAll()
if ($($servers.count) -gt 0) {
foreach ($server in $servers) { write-output "$($server.GetDirectoryEntry().cn)" }
}
}
As I mentioned, this is pretty handy for copying files to groups of servers, checking error logs via psloglist, doing inventory, and more.
