Connect to the VPN before login

For off-campus first-time logins to a newly-deployed computer, you will need to connect to the VPN before logging into Windows. 

Before connecting to the VPN, be sure that you are connected to the network. 

If working 100% remotely, this procedure should be completed periodically to ensure your PC remains established in Active Directory.

Follow this process only if you are performing a first-time login from off-campus.

Step-by-step guide

1. At the Windows login screen, press Ctrl-Alt-Del if prompted, then click the following icon in the lower-right corner: 


2. When the Cisco AnyConnect Secure Mobility Client window appears, enter and click Connect. Note: is also valid.

  This /SBL URL is only intended for Start Before Login VPN. Normal VPN logins should use or with standard CAS authentication.

3. You will be prompted for the following:

Username: Your Clarkson AD username

Password: Your Clarkson AD password

Duo: Type one (1) of the following words: push, sms, phone; OR the current 6-digit Duo passcode shown in your Duo app. Choose the word that corresponds with your preferred method in Duo. Examples are shown here.


5. You will then be returned to the login screen. Enter your Clarkson Active Directory credentials and submit.

You will remain connected to the VPN following the completion of your login. Your profile will be downloaded to the PC, so this process is only required the first time. However, it is also recommended that this process be repeated periodically.
