If you try to access a NTLM secured website on IIS via Chrome you will have to authenticate.
If you use the following structure user@domain the server is getting in an authentication loop or something, and will continue to produce like 1500 401 errors per second till your disk is full. After restarting the service you can get out of the loop.
How do I prevent for now Chrome brouwsers to be able to login? Block the browser?
What version of Chrome are we dealing with? I know the latest version I just downloaded (188.8.131.52) doesn't seem to have any problems. I tested it against an internal website (sharepoint) which uses NTLM to secure it. Could it be an older version that is causing the problems or a Chrome spoof?
