Is anybody else having AD account lockout issues?

[Windows Central Question]

Ever since build 10130 our domain accounts get locked due to too many invalid attempts from the laptops. Issue exists on multiple laptops, fresh build, removing from GPOs, disconnecting all network connections does not help.

I am running Windows 10 10240, but the AD account lockout issue started for me on 10166. I also have Office 2016 preview installed, but had no issues until I went to 10166.

This doesn't always happen, but as soon as I notice my account is locked out, I can reproduce it at will by simply accessing a network share. Today I closed out every application and killed as many third party processes as I could find. As soon as I access even \\dcname\sysvol, it locks my account out immediately. I've reviewed our DC's and the issue is definitely coming from this machine. I can use another Win 8.1 machine without issue.

I ran some packet captures while accessing the share and I get a bunch of Kerberos errors:
KRB_AS_ERROR, KDC_ERR_PREAUTH_REQUIRED: Additional pre-authentication required*
KRB_AS_ERROR, KDC_ERR_PREAUTH_FAILED: Pre-authentication information was invalid

Any help would be great!

A colleague just had an account lockout issue with 10240.
This went away when Skype for Business was closed.
Might be worth a try...
