Hi guys, Prior to ERAC/ERAS 4.x, I was able to use NTLM authentication for client updates. Since the upgrade, all my clients are unable to update using NTLM. I believe 4.x is using NTLM v2. ERAS/ERAC: v4.0.138 NOD32 client: v220.127.116.11 Do I need to input domain name in the username in the client side? Or is there anything that i missed out? Currently falling back to basic authentication.
