Network Access Denied

It appears you are attempting to access a protected online resource that for data security reasons can only be viewed by computers on the Stanford University or Stanford Medicine network.

You have been redirected to this page because you are currently using a computer on a network that is not recognized as a trusted campus or hospital network.

Stanford faculty, students and staff

To access the resource you are seeking from your current location, you will need to use Stanford's Virtual Private Network (VPN). This remote-access technology creates a private encrypted connection over the Internet between a single host and Stanford's private network. Stanford's VPN service is only available to faculty, students and staff with an active SUNet ID.

Installing a VPN client on your off-campus computer is a simple process that should only take a few minutes. Directions can be found here:  

SHC and LPCH employees

If you are an SHC or LPCH employee, you may gain remote access from off campus via their respective websites.

For SHC: Call the SHC Help Desk at 723-3333

For LPCH:  If you have any problems with this or questions, you may call the LPCH Help Desk at 498-7500

Tips for Installing your VPN client

Here are some possible problems with the VPN client and potential resolutions for them:

1. Problem: VPN client won’t start up.

Resolution: VPN client may need to be reinstalled if its files have become corrupted.  The best practice for this is:

For Windows machines – uninstall the VPN client through Control Panels -> Add/Remove Programs and uninstall Cisco Systems VPN Client.  You will want to be sure to remove all files.  After this you can re-download the VPN client and reinstall it.

For Mac machines – Drag the Cisco VPN Client folder to the trash, re-download the client and reinstall it.

2. Problem: VPN client gives an error or fails to prompt for a username and password after “Connect” is clicked.

Resolution: Ensure that your network is connected by trying to browse to a website in your web browser.

If an error is given, your connection profile may have become corrupted in which case you should delete the connection key, re-download it and re-import it.  If the Stanford Public VPN connection key has become corrupted, you will need to uninstall and reinstall the VPN client as specified above.

3. Problem: VPN client is not accepting your SUNetID and password.

Resolution: Verify that you are typing in your correct SUNetID and password by trying to login to 

If that works and your SUNetID and password previously worked with the VPN client (and your SUNet ID password works for other authenticated sites), it is possible that the VPN server has lost synchronization with your latest SUNetID password.  Try changing your SUNetID password at  This will force a re-synchronization with the VPN server.  Note that if you change your SUNetID password, you will need to update that password in your email client (Outlook or Mail) and your mobile device.

If your SUNetID and password have never worked with the VPN client, you may not be part of the access group for that VPN profile.  Contact IRT for further assistance.
