We are experiencing frequent account lock outs for a user and would appreciate some suggestions to find the root cause.
The user accessed the said account through VPN, where he was prompted for a Password change.
After this, the account has been continuously locked out, several times a day.
We tried using a tool called Netwrix, which spotted the account cache on the proxy to be the cause. But even after clearing the cache, the same result. Appreciate any inputs on this.
We checked, the user is not accessing his account from any mobile device
We also tried updating Microsoft updates
