Filemaker 11 Server authentication error
We are running Filemaker Server 11 in our small office. Filemaker has its own server and is set up to log our users on automatically by accessing the Directory Services on our other server Windows SBS 2011.
Most of the time the loggin on happens without issue, however, roughly weekly when a user attempts to access a database it asks for a username and password, and then nobody in the office can access the database.
The staff have found that the only way to fix the issue is to restart the server running Filemaker Server.
What could be causing these regular (but not constant) errors? Any help you can give would be much appreciated.
