Behavior:
The database has been moved and now DocuWare servers will not start.
Solution:
The settings file of the Authentication Server contains the name of the database server and the login credentials.
If the database server has been moved, the information has to be adapted.
The settings file "DWAuthenticationServer.exe.settings" is located in the installation path of the Authentication Server.
In this file you'll find following section, where you need to apply the changes:
...
<Connection>
<ID>8b25dd99-ec93-4082-9a93-dca5034b0534</ID>
<Database>DWSYSTEM</Database>
<Port>-1</Port>
<Driver>SqlClient</Driver>
<Name>AuthenticationSettings</Name>
<Server>SERVERNAME</Server>
<Source type="DIRECT">ASConnection</Source>
<Login trusted="false" encrypted="true">
<UserName>USER</UserName>
<Password>PASSWORD</Password>
</Login>
</Connection>
...
Adapt the appropriate parts, save and start Authentication Server only.
Now open DocuWare Administration and amend all DocuWare database connections there as well!
