A. Acctinfo.dll is a DLL that extends the functionality of the Microsoft Management Console (MMC) Active Directory Users and Computers snap-in. Acctinfo.dll is included in the Windows Server 2003 Resource Kit tools. Installing acctinfo.dll adds the Additional Account Info tab to the user object's Properties page. As the figure at Figure shows, this tab contains a variety of information, including

  • the last time the password was set
  • domain password policies
  • password expiration date
  • lockout status
  • last good and bad logons

To install acctinfo.dll, run the command

regsvr32 acctinfo.dll

If the command doesn't work (i.e., if Regsvr32 can't locate acctinfo.dll), specify the full path to acctinfo.dll--for example, regsvr32 C:\program files\windows resource kits\tools\acctinfo.dll (the folder in which acctinfo.dll is usually located).
