|Bug ID Number||BUG-000083324|
|Submitted||February 3, 2015|

|Applies to||ArcGIS for Server|
The ArcGIS Web Adaptor unregisters or loses its configuration, and resets to the default or blank configuration in the webadaptor.config file.
The ArcGIS Web Adaptor sends periodic messages to verify connectivity to the ArcGIS Server. If there is a disconnect or loss of communication during these periodic messages, the web adaptor loses its configuration. This happens in most cases where communication may be across the network, but also less frequently when the Web Adaptor is installed on the same machine as the ArcGIS Server.
Note: This issue is fixed at 10.3.1. This issue can be resolved by maintaining a copy of the webadaptor.config file.
Once a copy of the webadaptor.config file is saved, it is no longer necessary to reinstall and reconfigure the web adaptor if the issue reoccurs.
