The documentation below shows the process of setting up the AnyConnect application to connect to CU-Boulder's VPN service for Windows users.

This tutorial applies to the following operating system(s):

Important Note

A recent Microsoft update has created an issue with the Cisco AnyConnect application, prompting a "failed to initialize connection subsystem" error message to appear when connecting. To fix this issue, use Microsoft's Fix It solution after installing AnyConnect.

Step 1

Download and install Cisco AnyConnect for Windows.

*Note: If you are currently using AnyConnect for another VPN, you do not need to reinstall the application. You only need to add the new profile, as shown in the remaining steps.

Step 2

Open the Cisco AnyConnect Security Mobility Client application.

*Note: If opening from Program Files, double-click vpnui, located in the Cisco -> Cisco AnyConnect Security Mobility Client folder, to launch the application.

Step 3

Type vpn.colorado.edu into the VPN: textfield, then click Connect.

*Note: Advanced users and system administrators should enter vpn.colorado.edu/limited in this field. Custom VPNs in the format of vpn.colorado.edu with /thecustomaddress appended should also be entered in this field, if applicable.

Step 4

When prompted to login, enter your CU Login Name and IdentiKey password, then click OK.

Step 5

You will now be connected to the CU-Boulder VPN service. All your internet activity will be routed securely through the VPN.

*Note: For future connections, use steps 2 - 5. The vpn.colorado.edu connection can now be selected from the the drop-down menu in step 3.

Step 6


To disconnect, reopen the client by clicking on the AnyConnect icon from the bottom right task bar.

Step 7

Click the Disconnect button to end your session.
