New NMR File Server (NMRFS)

How to access the new NMR File server, NMRFS

You can connect to the NMR file server from any computer. 

  • On campus, you can be connected to either a wired University network or to the wireless IllinoisNet network. 
    • On-campus wireless connections to either the "Eduroam" or "IllinoisNet_Guest" networks will not work. 

  • Off-campus connections to the server requires use of the University VPN.   This creates a secure connection between your computer and the Illinois campus network. If you do not already have the VPN software installed on your computer or need assistance with this, please see VPN Installation Instructions. 

Instructions for Windows

  2. Open the Run box - you can either:
    • press the Windows logo key + R, or
    • type Run in the search box at the bottom of the screen and select the "Run" app

      Run command

IMPORTANT NOTE:  This is not recommended for off-campus computers - if you're curious as to why, see the FAQ section below:

  1. Right-click on the file share, and select Map Network Drive.
    • NOTE: on Windows 11, when you right-click on the file share name, you'll first need to select Show more options, then on Map Network Drive

FAQ (Frequently asked questions):

Why can't I see any data?  Who do I contact if I have problems getting my data? 

If you get an error when trying to connect to the server:

  • Contact SCS Computing staff (email: for connection issues. 
  • Be sure to include any error messages, screen shots, URLs or other specific data to help us determine what may be happening.  

If you are able to successfully connect to the server (meaning you see the list of instruments inside the SHARES folder) but do not see ANY group folders inside of each machine's folder:

  • Your permissions are not set correctly
  • Contact the NMR staff (
  • Let them know who your advisor is and that you do not see any data at all.  

Why is it a bad idea to map a network drive on a Windows computer if I'm off-campus? 

Several reasons:

  1. Slow booting: When a Windows computer boots, it tries to reconnect all network drives before giving you an opportunity to log in.  Since the mapped drive only works when you're using the campus VPN, you'll have to wait the 45-60 seconds for the connection to time out before you'll be able to log in.  This gets old rather quickly. 

  2. Lock-outs after changing password: Generally, a mapped drive is setup using cached credentials.  If you change your University password, the cached credentials are NOT automatically updated.  This means that every time Windows tries to connect to the mapped network drive (when you're connected to the VPN), it's using an out-of-date password and your Active Directory account WILL GET LOCKED OUT.  The only way to fix this is to remove the mapped network drive, and re-connect to it using your updated credentials.  

Alternatively, Windows only checks if items in the "Quick Access" bar are accessible when they are accessed.  So adding a shortcut to your "Quick Access" bar (Option A) does NOT make your logins take any longer regardless of VPN status.  

Who do I contact if I have problems in the NMR lab obtaining data or using the instruments? 

The NMR Laboratory staff ( can help you with questions about obtaining scientific data using the instruments and computers in the NMR lab.
