The Good news is setting the default password policy for a domain is really easy. Microsoft did introduce Fine Grain Password Policies with Windows Server 2008 however this can only be set based on a security group membership and you still need to use the very un-user-friendly ADSI edit tool to make the changes to the policy.īelow I will go through how you change the default domain password policy and how you then apply a fine grain password policy to your environment. This catches a lot of people out as they apply a password policy to an OU in their AD thinking that it will apply to all the users in that OU…. #Passwords plus windows cannot set catagories update#"It will not rollback the changes to the current password if it is unable to update it in Active Directory.One strange thing that still seems to catch a lot of people out is that you can only have one password policy for your user per domain. "We first change the password locally and then update it in Active Directory," the Directory Services Team explained. ![]() When machine passwords do get changed, the change takes place first on the device and second on Active Directory before the machine password change process gets completed. ![]() The machine password reset process gets postponed automatically if a client device can't connect to an organization's domain controller, which ensures that secure channel issues don't occur. In essence, machine password resets get driven by Windows client devices, not by Active Directory. #Passwords plus windows cannot set catagories how to#Microsoft's announcement didn't offer any clues on how to address such scenarios, alas. This is rare, and not normal, but if it happens, you may be on the road to secure channel issues. The local device's registry may get updated with a new password - but the DC won't be updated. In that case, the client password change process may not bail-out. However, we have seen some issues in the past if there was "intermittent" connectivity, and a DC is resolved/found, but something blocks unfettered communications to the DC (such as a firewall rule or some other connectivity issue). Organizations could also see a secure channel issue with remote Windows clients if those clients have intermittent connectivity to an organization's domain controller, Microsoft admitted. It disrupts the trust relationship of the network connection. If it could contact the DC but not succeed in changing its password for 60+ days, then it will have a secure channel issue.Ī secure channel issue is bad, of course. If the machine was unable to communicate with a domain controller, it doesn't try to change its password - for example if it was a laptop running at home with no VPN for 4 months. Here's how the Directory Services post described that scenario: A problem can occur, though, when the client device can connect to an organization's domain controller but a machine password doesn't get changed for more than 60 days. No machine password resets are attempted if the client machine can't connect to an organization's domain controller. It's the Windows Netlogon service on client devices that initiates these machine password resets. Windows client devices are set by default to request machine password resets every 30 days, unless IT pros change that default. It differs somewhat from the password reset process enacted via Active Directory. In essence, a client device's machine password reset mechanism is its own thing. That process was explained 11 years ago in this Directory Services blog post, which got recently updated by Microsoft. The answer from Microsoft is that there won't be issues because of how the machine password reset mechanism works in Windows client devices. Will there be issues when people come back in to work?" This is the scenario we're seeing concerns about - "My users have their PCs at home, without VPN/connectivity, for well-beyond the machine password lifetime in AD. Microsoft described a common question it's been getting of late about machine password resets for remote workers, which is different from personal password resets. Machine Password Resets for Remote Workers A somewhat unaddressed issue is business reliance on the security of home routers that likely are being used by remote workers to connect to a company network. ![]() Microsoft also recently addressed how patching remote clients can be affected by the use of VPNs in terms of the potential network bandwidth drag. Cybersecurity and Infrastructure Security Agency (CISA) to support remote workers. Organizations may have lacked virtual private network (VPN) support, which is considered a requirement by the U.S. Employees took company laptops and PCs home, but IT preparations to support remote work scenarios may have lagged. Microsoft this week explained how the machine password mechanism for Windows systems works, and the effects when people have shifted to working remotely.Ī shift to remote work likely happened for many organizations in March due to the coronavirus disease pandemic. ![]()
