ADComputerobject OperatingSystem empty

I have a small PowerShell script, which should show me the operation system of different Servers in the Active Directory. All information are in the computer object, but when I get the reply from the PowerShell script it is empty.

Any ideas what could be the problem?

Script:

Get-ADComputer -Filter {name -like "ServerName"} -Properties 'OperatingSystem', 'OperatingSystemVersion' -Server DomainName:Port

Output:

DistinguishedName      : DistinguishedName      
DNSHostName            : DNSHost.domain
Enabled                : True
Name                   : ServerName
ObjectClass            : computer
ObjectGUID             : ObjectGUID     
OperatingSystem        : 
OperatingSystemVersion : 
SamAccountName         : SAMAccountName$
SID                    : SSID
UserPrincipalName      :

  • OperatingSystem
  • OperatingSystemHotfix
  • OperatingSystemServicePack
  • OperatingSystemVersion

as other fields, are not replicated in the Global Catalog (see https://learn.microsoft.com/en-us/windows/win32/adschema/a-operatingsystem and following sections). Hence you can't get these fields when requesting the GC (-Server DomainName:Port). You can retrieve them only by requesting directly the domain (-Server DomainName).

I have exactly the same problem (PS7 with a lot of module), the OperatingSystem parameter is available, but hidden. Nevertheless, filtering on OperatingSystem is possible but not displaying it

Get-ADComputer -Filter { operatingSystem -Like '*Windows Server*'} -Properties operatingSystem -Server $env:USERDNSDOMAIN

result is realy filtered !

DistinguishedName : CN=SRV-01,OU=Serveurs,DC=contoso,DC=com
DNSHostName       : SRV-01.contoso.com
Enabled           : True
Name              : SRV-01
ObjectClass       : computer
ObjectGUID        : 46306f78-9833-40c2-bb9c-06461462b
OperatingSystem   :
SamAccountName    : SRV-01$
SID               : S-1-5-21-184956565-601246437-303096148-4584

to really know the OperatingSystem value I read the remote registry HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProductName
