Sheridan Posted October 16, 2013 Posted October 16, 2013 Since we started rolling out Windows 7 with IE10 in anger, we've noticed a huge increase in locked AD accounts - the user will get the usual dialogue box asking them to authenticate. We use Smoothwall as our filter but I don't think this is the problem as it hasn't changed recently and the lockouts seem to only occur with users on the Win7+IE10 PCs Short of removing IE10 I can't find any other problems, anyone else noticed anything like this?
aleach2 Posted October 16, 2013 Posted October 16, 2013 (edited) We had the same problem. What we had to do is in smoothwall go to Web Proxy > Web Proxy Settings > Click Advanced > In Web Filter Options make sure "Interrupted NTLM connections are caused by non-standard Web browser behavior. Disable this option if restrictive Active Directory account lockout policies are in operation." is disabled. This fixed the problem for us. Hope this helps. Adam Edited October 16, 2013 by aleach2 1
Sheridan Posted October 16, 2013 Author Posted October 16, 2013 Ahh I'm glad someone else has had this problem then! I'd assumed smoothwall wasn't the issue here - but I'll try that setting and see how it goes - thanks for that.
aleach2 Posted October 16, 2013 Posted October 16, 2013 Like yourself we never had a problem with lockout policies until we came back in September them BOOM loads of students couldn't logon, just like yourself. Spoke to Smoothwall support and they said to make the change mentioned and we haven't had a problem since. Well except for the real numpties that can't remember their password.
Sheridan Posted October 16, 2013 Author Posted October 16, 2013 Yeah we always have the 'regulars' who lock themselves out but this was a massive increase! The only common factor was IE10 so I was working on the asumption it was that. Its both staff and students who have the issue here, hopefully it will fix our problem too.
aleach2 Posted October 22, 2013 Posted October 22, 2013 @Sheridan: Did the solution I suggested work? Would be interested to know. Cheers,
Sheridan Posted October 22, 2013 Author Posted October 22, 2013 @Sheridan: Did the solution I suggested work? Would be interested to know. Cheers, I only made the change a couple of days ago but so far its looking really positive, far fewer lockouts and they are probably just the normal! Cheers for the info on that, I didn't think smoothwall was going to be the issue.
