DNS Changes Over Holiday Break

As you may have read previously on this blog or in the June 2010 IR Update (page 15), our Systems Team will be making changes to our DNS Infrastructure over the holiday break. These changes will add additional redundancy, scalability and security to our DNS servers, and should be transparent to all managed Windows and Mac workstations.

For those using unmanaged workstations on campus, you’ll need to change your DNS servers from 158.135.1.20 and 158.135.1.200 to 158.135.2.20 and 158.135.2.200. Starting January 2011, the legacy DNS server (158.135.1.20 and 158.135.1.200) will not resolve any internal SHSU domains (file and print servers, domain controllers, etc) or any external domain (google.com, msn.com, yahoo.com, etc.

How do you change these settings?
For a Mac:

  1. Open System Preferences.
  2. Click on Network.
  3. Edit the DNS Server to read: 158.135.2.20, 158.135.2.200
  4. Click on Apply. You may have to restart your computer after making these changes.

For a PC:

  1. Click on the Start menu and select Control Panel.
  2. Click on Network Connections.
  3. Right-click on Local Area Connection and select Properties.
  4. Highlight Internet Protocol (TCP/IP) and click on the Properties button. You can then update your Preferred DNS server to 158.135.2.20 and the Alternate DNS server to 158.135.2.200.
  5. Click on OK. You will most likely need to restart your computer after making these changes.
