I running ACS 3.3 over six months and running smoothly , Recently i got a error message from ACS server

From "External User Database" -> "Database Group Mappings" -> "Windows Database" -> Select "AD Domain" -> "add mapping" -> Got Fail Message "Failed to enumerate windows group , If you are using Active Directory consult the installation guide for information"

Anyone can tell me how to resolve the problem

Hi

You need to set logging to max, then manually re-start CSAdmin from the control panel. Try the UI page again then save the csadmin/logs/adm.log file.

Most likely something within your AD network has changed if ACS has suddenly stopped working.

Anyway, you may need to open a TAC case because tracking down AD problems can be long winded.
