Configuration information could not be read from the domain controller due to a DFS denial. The domain controller is currently in the process of migrating its configuration data to a new domain controller.
This has happened in the past, but the most recent incident happened in 2009 (see What I Learned in 2009). A company called Microsoft was using a similar denial tactic called a “Domain Name System (DNS) leak.” The DFS denial involved the DNS service leaking configuration information from the domain controller. The DNS leaking happened because the domain controller was storing its configuration data in non-standard locations.
The last time that happened was back in 2009, but it can happen again, and it’s happened a few times in the past. The most common reason for the disclosure to the outside world is when the domain controller changes its configuration. Changing the configuration files could be done by simply using Windows Explorer and viewing the file in the properties window.
In the past, configuration files were normally stored in the root directory of the domain controller. It was not possible to read the configuration file from the domain controller, so the data was not accessible. In that case, the data was still readable from the outside world, but the original application that made the change had to be rewritten.
The domain controller is the Windows server where all the domain objects are stored. It was the first computer that a user would connect to to access all the resources that they needed to run their computer. So, it was a very valuable resource for computers and computers had many different ways to access the domain controller. But the old configuration files were not readable from the domain controller, so they couldn’t be changed.
This change was made to improve security. The old configuration files were read only, allowing only a user with the appropriate privileges to read them. The new configuration file allowed only a domain administrator to change the configuration.
It seems that the old configuration files were actually writable by a domain administrator and the new configuration files are just a small, trivial change that could have been easily made by anyone. The change is in support of the fact that the old configuration files are not really useful for any computers other than the domain controller, which are the computers that control the domain.
The configuration files are the same for every domain. They are just a small tweak and probably not that hard to make. It may be that someone has figured out a way to make them work on computers other than the domain controller. There is no suggestion that it is a serious security flaw or that it has anything to do with security at all.
I’ve seen plenty of reports on forums and websites where computer users have reported that they can’t read the configuration information from the domain controller, and I’m sure that’s not the worst issue. It may be that this is a problem with the older versions of Windows and some users have been receiving a warning since the last time they updated. It’s possible the problem could also be with the newer versions of Windows.
Its possible that you could have your domain controller configured in such a way that it doesnt know what to do with configuration information that you provide it. This is a problem that could be caused by the fact that the domain controller has a configuration file with your configuration information, but the configuration file itself doesn’t allow the configuration to be read.
