WhoIs lookup from Windows command line

A WhoIs lookup will show the registration record for a domain name, and being able to run this right from the command line is really convenient.

This utility will run on Windows XP and higher (client) and Windows Server 2003 and higher (server).

Download the utility from the Windows Sysinternals site and copy it to the path that you want to use (probably C:\Users\MyUsername). After that you can run the WhoIs utility like this:

Name.com Android app – Domain name registration

Manage your domain names from your phone

UPDATE – Sadly, the Name.com Android app is no longer available 🙁

I’ve always liked using Name.com as a registrar, and now I have even more reason to. I stumbled upon their Android app recently, and its actually useful. They didn’t just make a marketing or sales tool, because there’s more to it than finding and registering new domains. You can also manage your existing domains, including renewals, nameserver and DNS changes, whois info, domain locking, payment options, and more.

Name.com Android App

You can get the Name.com Android app at the Google Play store, or scan the QR code below to download the app.

Domain Controller Troubleshooting with DCDIAG , REPADMIN , and NETDIAG

Useful tools for troubleshooting Windows domain issues

windows-server-01

DCDIAG

DCDIAG analyzes the state of domain controllers in a forest or enterprise and reports any problems to help in troubleshooting.

Details available at MS TechNet.

Example: dcdiag.exe /V /D /C /E > c:dcdiag.log

REPADMIN

Repadmin.exe is a Microsoft Windows 2000 Resource Kit tool that is available in the Support Tools folder on the Windows 2000 CD-ROM. It is a command-line interface to Active Directory replication. This tool provides a powerful interface into the inner workings of Active Directory replication, and is useful for troubleshooting Active Directory replication problems.

Example: repadmin.exe /showrepl dc* /verbose /all /intersite > c:repl.txt

Details available at MS TechNet.

NETDIAG

This command-line diagnostic tool helps to isolate networking and connectivity problems by performing a series of tests to determine the state of your network client. These tests and the key network status information they expose give network administrators and support personnel a more direct means of identifying and isolating network problems. Moreover, because this tool does not require parameters or switches to be specified, support personnel and network administrators can focus on analyzing the output rather than on training users how to use the tool.

Example (to be run on each DC): netdiag.exe /v > c:netdiag.log

Details available at MS TechNet.

Joining a VM to a domain – Windows 7 XP mode

XP Mode (the Windows 7 VM for XP compatibility) is set to NAT by default. This works for general internet access, as explained at technet.com: “NAT allows the host machine to act as an agent between the external network (e. g. Corpnet or Internet) and the VMs running on that host. The network will use the host’s IP address itself, which represents the group of VMs on that host, to communicate with the VMs.”

I ran into problems trying to join the virtual machine to a domain, as the VM could not see the domain controller. The fix is simply to change the network adapter on the VM. Here’s how:

1) Launch the VM (XP mode)

2) Select ‘Tools’>’Settings’ in the VM Toolbar

3) Select ‘Networking’ on the left

4) In the dropdown for your network adapter select your ethernet card

XP mode network adapter

Join Windows 2k3 AD Domain with Fedora Client

  • Set your hostname appropriately. Using the hostname command won’t stick after a reboot. The System>Administration>Network>DNS GUI will let you set the hostname and DNS servers. The hostname can be added to /etc/hosts as well.
  • Add your user and computer to Active Directory. If you haven’t already.
  • Join the domain. From the terminal, as root:
    net join -S DOMAINCONTRLR -UAdministrator%DomainAdminPass
  • Set up authentication. System>Administration>Authentication>User Information, check box for 'Enable Winbind Support'. Click on 'Configure Winbind'. Security model should be domain, add your Domain Controller by IP, click on 'Join Domain' and it should prompt you for the Administrator's password. Now go to the Authentication tab and do the same.
