Issue/Introduction

- Windows 7 Enterprise: Internet Explorer users are prompted to enter authentication credentials before allowing Internet access through the ProxySG
- Other Windows (XP, 7 Ultimate and below) are able to Authenticate through the ProxySG without being prompted for Authentication Credential

 

Resolution

Reason:

1. Windows 7 Enterprise has tighter security measures compared to Windows 7 Ultimate or lower / Windows XP...etc
2. Windows 7 Enterprise will not send NTLM credential to any untrusted URL/Sites.

 

Steps:
  1. To make Windows 7 Enterprise send NTLM credential to the ProxySG appliance, make the Internet Explorer trust the ProxySG Virtual URL.
  2. To do this, open IE browser and select Tools -> Internet Options -> Security -> Local Intranet > Advanced.
  3. Add IWA virtual URL (example "proxy1" without quote).
