I can get the last time a patch was applied. What I need is this info for ALL servers.

Question

Getting the last time a server was patched is a simple, single line of PowerShell:
     get-hotfix -computername seadcweb10 | sort InstalledOn | select -last 1
What I need is to get a list of *all* the servers in Active Directory, and get this information for each.
I've tried variations of foreach , but I get errors.
foreach ( $p in Get-ADComputer -Filter 'OperatingSystem -like "Windows *Server*"' ) { get-hotfix -computername $p.Name | select -last 1 }
Get-HotFix : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)
At line:1 char:97
+ foreach ( $p in Get-ADComputer -Filter 'OperatingSystem -like "Windows *Server*"' ) { get-hotfix <<<<  -computername
$p.Name | select -last 1 }
    + CategoryInfo          : NotSpecified: (:) [Get-HotFix], COMException
    + FullyQualifiedErrorId : System.Runtime.InteropServices.COMException,Microsoft.PowerShell.Commands.GetHotFixCommand
What am I doing wrong?

Hi
The RPC server is unavailable
This error  comes when any server is not pingable.
Make sure you are able to ping to all server from the server you are running the script.
Then give a try to below script :
foreach ( $p in Get-ADComputer -Filter {OperatingSystem -like "Windows *Server*"})
get-hotfix -computername $p.Name | select -last 1
