Q: If using GZN (Global Names Zone), do your clients need a WINS address configured on them?

No they do not. The idea behind the GlobalNames zone in Windows Server 2008 is that no client configuration is needed. Just remember that you need to meet these requirements.

· DNS Servers must be Windows Server 2008.
· Global Names Zone must be enabled (DNSCMD /config /enableglobalnamessupport 1) on each DNS server.
· A forward lookup zone named GlobalNames must be set up on each DNS server that
· · · Is active directory integrated
· · · Does not support dynamic updates (recommended)
· You must provide a CNAME record mapping the client name to its FQDN.

When a client makes a single name request to a DNS server, DNS will check all its zones to try and match it to a FQDN. This will not work. After DNS has exhausted all its zones, it will look in the Globalnames zone. There, should it be present, it will locate a CNAME record for that single name. It will point to the FQDN record in the forward lookup zone. DNS will now return the IP address to the requesting node.

How to run GPResult on a remote client with PowerShell

In the past, to run the GPResult command, you would need to either physically visit this client, have the user do it, or use and RDP connection. In all cases, this will disrupt the user. First, you need PowerShell remoting enabled on the target machine. You can do this via Group Policy . Open PowerShell and type this command. Invoke-Command –ScriptBlock {GPResult /r} –ComputerName <ComputerName> Replace <ComputerName> with the name of the target. Remember, the target needs to be online and accessible to you.

Set up your Environment to utilize Invoke-GPUpdate

I’m sitting in O’Hare enjoying my 3 hour layover as I get ready to teach a Windows 10 class in Fort Wayne. I’m actually prepping for my class in Fort Wayne in a few weeks, 10982 Supporting and Troubleshooting Windows 10. This class is very much like the Windows 7 version that I used to teach so I decided to up the detail quite a bit. In the GPO troubleshootin chapter, I’m including a demonstration on how to use PowerShell’s Invoke-GPUpdate. I needed to make sure the environment is set up for me to be able to utilize this cmdlet. If you read the Notes section on Invoke-GPUpdate’s help file, you will see there are three firwall rules that need to be in place: Remote Scheduled Tasks Management (RPC) Remote Scheduled Tasks Management (RPC-ERMAP) Windows Management Instrumentation (WMI-IN) I decided to create a little PowerShell script to crea...

Where did a User’s Account Get Locked Out?

Updated: May 15, 2015 When this article was originally published, two extra carriage returns were add causing the code to malfunction. The code below is correct. My client for this week’s PowerShell class had a really interesting question. They needed to know where an account is being locked out at. OK, interesting. Apparently users hop around clients and forget to log off, leading to eventual lock out of their accounts. The accounts can be unlocked, but are then relocked after Active Directory replication. This problem is solved in two parts. The first one is to modify the event auditing on the network. The second part is resolved with PowerShell. The first part involves creating a group policy that will encompass your Domain Controllers. In this GPO, make these changes. Expand Computer Configuration \ Policies \ Windows Settings \ Security Settings \ Advanced Audit Policy Configuration \ Audit Policies \ Account Management Double click User Account Management C...
