Method 1: Enabling SMB1 support

This particular error is often an indication that SMB 1 support is disabled on the client’s machine. SMB (Server Message Block) is a common protocol commonly used across Windows. Several users have reported that the problem was fixed after they discovered that SMB1 support was disabled on the machine that was trying to connect to the domain.

For most affected users, re-enabling SMB1 via the Windows Features screen eliminated the error and allowed the computer to connect to the domain. Here’s a quick guide on how to do this:

1. Press Windows key + R to open up a Run dialog box. Then, type “appwiz.cpl” and press Enter to open up Programs and Features.

   

2. Inside Programs and Features, click on Turn Windows Features on or off from the left-hand pane.

   

3. In the Windows Features menu, scroll down through the list of features and make sure that SMB 1.0/ CIFS File Sharing Support and any associated sub-menu are enabled. Then hit Ok to save the changes.

Method 2: Uninstalling 3rd party firewall

As some affected users have pointed out, several 3rd party antivirus suites are known to be overprotective with the connections that they allow to go through. Some users dealing with the ‘following error occurred attempting to join the domain‘ error have reported that the issue was no longer occurring after they uninstalled the 3rd party firewall.

Some users are speculating that some external security suites are blocking some bi-directional ports that are used when a computer tries to connect to a domain for the first time.

Keep in mind that if you’re using a 3rd party firewall, temporarily disabling the firewall will not resolve the issue since the same rules will remain firmly in place. The only acceptable solution, in this case, is to uninstall the 3rd party firewall and see if the same error is still occurring.

You can follow this guide (here) to ensure that you completely uninstall the security program that you’re using.

Once the 3rd party firewall has been uninstalled, restart your computer and see if the issue is still occurring. If it’s no longer appearing, consider sticking with the built-in Windows Firewall or search online for specific steps on establishing exception rules for the ports used by the network devices involved in domain connectivity.

If this method wasn’t effective, move down to the next method below.

Method 3: Using a System Restore point

Note: A previous System Restore point will restore your computer to a previous point in time. This means that any changes made during the reverted period will be lost.

Here’s a quick guide on using the System Restore wizard to resolve the ‘following error occurred attempting to join the domain‘ error:

1. Press Windows key + R to open up a Run dialog box. Then, type ‘rstrui‘ and hit Enter to open the System Restore wizard.

3. Choose a system restore point that is older than the apparition of this issue and hit Next once again.

   

4. Click Finish to revert your machine to the older state. After a short while, your computer will restart and the restore point will be enforced at the next startup. With the older state in place, you should no longer encounter the ‘following error occurred attempting to join the domain‘ error.
