how can I query to multiple domain's computer account in powershell - csv

Question

I have bulk computer list in my CSV file with header of servers.
All these servers are different domains under single forest.
I need to get all these server attribute details like name and operating system, status.
I have created below script but that's not working..
Any help would be appreciated.
Import-Module ActiveDirectory
# For each domain in the forest
$domains = (Get-ADForest).Domains
$servers = Import-Csv "D:\temp\computer.csv" | % {$_.server}
foreach ($server in $servers)
{
foreach ($domain in $domains)
{
Get-ADComputer $server -Server $domain -Properties operatingsystem | select name,operatingsystem
}
}

HI
I have added my script like below:
#
Import-Module ActiveDirectory
# For each domain in the forest
$domains = (Get-ADForest).Domains
$servers = Import-Csv "D:\temp\computers.csv" | % {$_.server}
$DomainController = "DC2:3268" # 3268 is the commen port of global catalogue
$SearchBase = ((Get-ADDomain (Get-ADForest).RootDomain).DistinguishedName)
foreach ($server in $servers)
{
foreach ($domain in $domains)
{
Get-ADComputer $server -Server $DomainController -SearchBase $SearchBase -Properties operatingsystem | select name,operatingsystem
}
}
#
Getting below error now and also I have specified only samaccountname of computer not FQDS this time..
#### Error

You have to run your request against the global catalogue to find AD objects in the whole AD forest.
You need a server witch is supporting global catalogue. Choose one which is next to you.
Import-Module ActiveDirectory
#((Get-ADForest).GlobalCatalogs) | Sort-Object
Your script, a little bit modified
Import-Module ActiveDirectory
$DomainController = "ServerFromStep1:3268" # 3268 is the commen port of global catalogue
$SearchBase = ((Get-ADDomain (Get-ADForest).RootDomain).DistinguishedName)
foreach ($server in $servers)
{
Get-ADComputer $server -Server $DomainController -SearchBase $SearchBase -Properties operatingsystem | select name,operatingsystem
}
The same as 2 but able to processed FQDNs from server list.
foreach ($serverFQDN in $servers)
{
$Local:ServerName = (($serverFQDN -replace "\..*$", "").Trim())
if ($ServerName) {
Get-ADComputer $ServerName -Server $DomainController -SearchBase $SearchBase -Properties operatingsystem | select name,operatingsystem
}
}
