Today Exchange 2013 reaches the end of the road and it will transition out of extended support. Hopefully everyone has migrated to a newer version and/or Office 365. But experience tells me that will not be the case.
Hopefully no one will have Exchange 2013 published to the Internet either, but again experience says otherwise…
Please note that Microsoft will not provide technical support, time zon… Read the rest “End of Exchange 2013 Support”
Manually starting up lab VMs is painfully slow, and since many organisations will implement management policy to auutomatically shut them down to save costs you may find yourself powering them on a lot...
While you can set up automated tasks to power them on, not all really need to be running every day. For example, I always want the DC's running so they are able to maintain replication and there … Read the rest “Quick Tip – Easily Start All Azure VMs In A Particular Resource Group”
Azure AD Self Service Password Reset (SSPR) has the ability to restrict which group of users are able to perform SSPR tasks. It is a slightly limited administrator control as only a single group can be selected. Azure AD administrator roles are able to perform SSPR even if they are not in scope of the selected group.
They typical user experience is that the person goes to https://aka.ms/SSPR and … Read the rest “Out of SSPR Scope User Experience”
A common issue when deploying Exchange Online Protection (EOP) and Microsoft Defender for Office 365 (MDO) with on-premises Exchange is making Exchange aware of the EOP spam filtering. This is because EOP uses slightly different logic to stamp the spam results etc. into the message. Exchange Server needs to be aware of this so that it can take action upon those settings.
Active Directory synchronization was designed not just to move objects from on-premises AD to Azure AD, but to give administrators precise control over how identities were matched, transformed, and filtered. This is not a new thing. It dates back to very early days of Microsoft cloud hosted email, both commercial and educational orientated. Azure AD Connect evolved from earlier solutions such as… Read the rest “Azure AD Connect Sync Options”
Self Service Password Reset (SSPR) in Microsoft Entra ID is one of those features that often goes unnoticed until it is urgently needed. It gives end users the ability to securely reset or unlock their account without calling the helpdesk, while administrators benefit from reduced support costs and improved security posture. Ideally users will have to use MFA to perform SSPR. This means that lame… Read the rest “SSPR Screenshots – December 2022”
The November 8, 2022 and later Windows updates address a security bypass and elevation of privilege vulnerability with Authentication Negotiation by using weak RC4-HMAC negotiation.
This update will set AES as the default encryption type for session keys on accounts that are not marked with a default encryption type already.
To help secure your environment, install the Windows update that is dated … Read the rest “Kerberos Issues November 2022”
Active Directory Federation Services (AD FS) uses endpoints to provide access to features. There are a series of different endpoints which each serve a different purpose from password reset, publishing federation metadata or multiple web services protocols. It is important to ensure that only the required features are actually enabled, and also if those features are to be made available internal… Read the rest “Check If AD FS WSTrust Endpoint Enabled”
Having to host, upgrade and manage WordPress is not really my main job. The various posts over the years will provide a small clue that other things take up most of my time and are my day job. Life was certainly easier when TechNet was still around as a dedicated team ran the MSDN and TechNet blog platforms and provided all of the infrastructure support. All I had to do was write the posts.
Alas… Read the rest “WordPress Linux Web App Poor Performance”
Extended Protection (EP) was added to Windows back in 2009 as a new security feature. This feature enhances the protection and handling of credentials when authenticating network connections using Integrated Windows Authentication (IWA).
The update itself does not directly provide protection against specific attacks such as credential forwarding, but allows applications to opt-in to Extended Protect… Read the rest “Updated Guidance On Exchange Server Extended Protection”
