Fixing Lansweeper Active Directory USER LDAP Syncing Error

In our organization we use lansweeper for ticketing and system inventory and management.  Recently we had an issue where our AD users would not sync with lansweeper.  The error shown was that the LDAP Server was unavailable

LDAP ERROR

The issue was caused by using a preferred domain controller that had died.  Theses settings are under "Scanning Targets"

We removed the Preferred domain controller

And setup a new scan

Setup a new scan after the preferred ad controller has been removed

Lansweeper Syncing with AD

After the scan the Users started to sync with the AD Controller again.  However having had this issue once before, you may need to reboot the lansweeper server if the users continue to have the LDAP error after the rescan.  After the reboot the LDAP Error should be gone.
