Users were reporting that their Windows domain accounts were being locked out.
After much investigation, the following was discovered.
- When you map a drive with Windows 7, it will try to connect to the “mapped drive” with your logged in credidentals.
- If the server you’re connecting to isn’t part of your domain, it will generate an Authentication error.
- Collect enough of the Authentication errors, and your domain account (ie. DOMAIN\UserID) gets locked out.
The work around is to use a DIFFERENT user account to your domain account. Better yet, integrate your Samba server into your AD Domain.
While the issue about was reported by users trying to connect to a Samba server, I’m guessing you could see it with other network devices as well.
