You may get error while trying to access Active Directory on the below line

searchResultCollection = directorySearcher.FindAll();

Kindly check the AOS instance (In service) whether its running under a Network Service Account, which did not have all the permissions to deal with the Active Directory.

To resolve this issue kindly change the login method of your service to use the local service instead of the Network Service.
