Campus Network Resource Troubleshooting

On-campus (or VPN) access to Middfiles, Miisfiles, and Papercut printing servers, as well as remote desktop connections, require a device's network configuration to have network access to those resources. Operating system features and/or changes to network settings may interfere with those connections. This article addresses some of the known issues and fixes, assuming the computer or device in question is already connected to the campus network (via Ethernet, MiddleburyCollege Wi-Fi, or VPN). 

Additional tip: using the fully qualified domain name (fqdn) for a resource is always advisable. Ex. rather than \\walnut\middcolor to connect to a printer, use \\\middcolor


Printer Installation Issue

Symptom:  Can't see the list of printers with Mobility Print? (macOS or Windows). iOS "No AirPrint Printers Found"

  • DNS Cause: Alternate DNS (domain name service) settings may prevent discovery of on-campus print servers (and file servers)

DNS Fix: remove manually added DNS server entries and allow the device to get DNS server information automatically when leasing an IP address. How To Geek's The Ultimate Guide to Changing Your DNS Server tells how to manually set DNS server settings; removing them will cause the device to retrieve DNS server settings via the Internet Service Provider ( when on campus).

  • Private Relay Cause: (macOS, iPadOS, iOS) iCloud Private Relay prevents the Mobility Print service from discovering on-campus printers.

Private Relay Fix: Turn off Private Relay for a specific network on your Mac as described below.  See Apple tech article on private relay for more details if needed.

In macOS Ventura or later:

  1. Choose Apple menu > System Settings.
  2. Click Network in the sidebar, then click the network service that you're using (such as Wi-Fi) on the right.
  3. Click the Details button Details button next to the name of the network that you're connected to.
  4. Turn off Limit IP address tracking.

In macOS Monterey:

  1. Choose Apple menu > System Preferences.
  2. Click Network and select the network from the list to see more options.
  3. Click the checkmark next to Limit IP Address Tracking


File Server (middfiles / miisfiles) or Remote Desktop Issue

Symptom:  Server not available / reachable.

See DNS Cause and DNS Fix.
