What happens if the Domain Controller is offline for too long?

For those playing with networking at home and who have an Domain Controller with Active Directory set up (although it would not be needed) and regularly shut down that main server it is interesting to know if it has any side effects.

As long as you do not keep the Domain Controller shut down longer than the days set for the Active Directory forest's tombstone lifetime you should be safe.

ADSIEdit can be used to check the set tombstoneLifetime for that particular server. The default for Windows 2008 R2 and upward is 180 days. See the linked TechNet article on how to determine the tombstone lifetime for the forest.

How to read an assembly.dll.config

There is the common misconception that only a app.exe.config can be read in .NET C#. The truth is that the app.config is automatically read, while any other (correctly formed) app.config XML file can be read "manually". To open a named config file: Reference System.Configuration.dll assembly Using System.Configuration Create code like: Configuration GetDllConfiguration(Assembly targetAsm) { var configFile = targetAsm.Location + ".config"; var map = new ExeConfigurationFileMap { ExeConfigFilename = configFile }; return ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None); } Sources: stackoverflow: Reading dll.config (not app.config!) from a plugin module Keywords: .NET, C#, app.config, dll.config, ConfigurationManager
