Exception occurred while enumerating Organizational Units

Hello,

I have a problem listing Organizational Units in my AD. Prompt: "Exception occurred while enumerating Organizational Units"

Newest build of ServiceDesk Plus 14970 is installed. AD Account password re-checked and retyped. Delta Sync and Full Sync working fine. Firewall rules checked - traffic is not blocked.

Kindly asking for help
