ARCHIVED: What is the tool that disables LM/NTLMv1, and where can I get it?

Due to security flaws that can allow unauthorized access to restricted resources, UITS has disabled support for the LAN Manager (LM) and NT LAN Manager Version 1 (NTLMv1) authentication protocols. Since certain network resources, such as printing to Residential Technology Center (RTC) printers or mapping network drives, depend on network authentication, you need to run a tool UITS created to configure your computer to disable insecure LM and NTLMv1 authentication protocols. You can obtain this tool free of charge from IUware.

Note:
If your Windows computer is joined to Indiana University's ADS domain, you do not need to run this tool. To see if your computer is joined to the ADS domain:

Windows 10

  1. Search System in the Start menu.
  2. Select System.
  3. On the next screen, under "Computer name, domain, and workgroup settings", look for "Domain:". If you see "ads.iu.edu", your computer is joined to the ADS domain. If not, you may need to run the tool.

    If you see "Workgroup" instead of "Domain:", you may also need to run the tool.

Windows 8.x

  1. Open Desktop mode.
  2. Press Win-c, and then click Settings.
  3. Click PC Info, and the system will display whether or not it is in the ADS domain.

Windows 7

  1. Right-click Computer, located on your desktop or in your Start menu, and select Properties.
  2. On the next screen, under "Computer name, domain, and workgroup settings", look for "Domain:". If you see "ads.iu.edu", your computer is joined to the ADS domain. If not, you may need to run the tool.

    If you see "Workgroup" instead of "Domain:", you may also need to run the tool.
