What to do when you see Windows code 52

Networking errors can be a bit tricky to resolve, especially on larger corporate networks. There may be more layers to sort through on a large AD network than there are on a simple home network.

Here are the basic steps to take to resolve Windows error code 52:

  • If you are connecting to a Windows server network and are receiving error 51, the server may be the source of the problem.
  • Log into the server and Right Click on My Computer.
  • Click on Manage.
  • From the menu that pops up choose the Services and Applications option.
  • Navigate to services and scroll down through the list until you see the Server service.
  • If the service is not started, right click on it and choose Start.
  • If the service is already running, right click on it and choose Stop and then Start after it has completely stopped.

Restarting or starting the Server service on a Microsoft Windows Server should resolve this issue.

If you still experience this problem after taking the steps laid out above, you may want to check the Windows names given to the computers on your network. This is only feasible on a small, home network, so if your network is larger, you may have to use server utilities to do this. Check the names of your computers. Many people will pick a common name like, “My PC” and accidentally name more than one computer the same thing. If there are computers with the same name trying to join the same work-group or domain, you will continue to get these error messages. Change the name of the newer computer that you are trying to connect to the home network.
