Leave Domain: “A general network error occurred’

KB ID 0001738

Problem

After a recent lab on the test bench, I ended up with a 2008  x32 standard server. It took me a while to get this setup and running, so I wanted to keep it (or turn it into a VMware template should I ever need  another). But first I needed to ‘remove it’ from  the domain it was in. However, when attempting to do so this happened;

A general network error occurred

Computer Name /Domain Changes

The following error occurred validating the name “Host-Name”
A general network error occurred

That stinks of DNS? But the machine could resolve DNS, ping the domain name, was authenticated to the domain, and could ping itself by netbios name and FQDN?

Leave Domain (via Command Line)

With modern servers and clients we can simply ‘force’ a machine out of the domain with some PowerShell. In an old machine like this (2008 ran Powershell version 1 natively) those commands are not open to us. So to solve the problem I had to go a little more ‘old school’

Remember – You will need to either know the local administrator password, or a local account with administrative access before you drop it out of the domain, (or post reboot you wont be able to login!)

Open an administrative command window, and execute the following command;

netdom remove %computername% /domain:{your-domain-name} /force

leave domain via command line

This will remove the machine from the domain, and drop it in a workgroup that that has the same name as the domain (in this  case TESTBENCH).
