I should have posted this previously, so apologies to those who attended my recent session on AD Troubleshooting, Diagnostics and Recovery. Relating to the demonstration for registering and using the AcctInfo.dll to add a new tab to the Active Directory Users & Computers tab for users, the account lockout tools can be downloaded from here. Once downloaded, you need to copy AcctInfo.dll to an appropriate place (such as \windows\system32) and register it (Start/Run regsvr32 c:\windows\system32\acctinfo.dll). Restart ADU&C, and open a user object. You will now see the new tab appear to assist in resolving account lockout issues.
