How to resolve Dir Sync error “duplicate UserPrincipalName conflict”

I was recently prompted about a Directory Sync error witting Microsoft 365 Admin Center. The user account had the message “We detected a duplicate UserPrincipalName conflict on the value user@domain.com. All attribute values need to be unique across objects. To resolve this conflict, first determine which object should be using the conflicting value. Then, update or remove the conflicting value from the other object(s).” A little research revealed the account had been created, deleted, and then recreated in a short period of time. I suspect directory synchronization may have occurred at some point between the creation and deletion resulting in the error.

How to increase vCenter Appliance web client session timeout

As of vSphere 6.7 Update 1, the vCenter vSphere Client (also referred to as the HTML5 client) has reached feature parity with the now deprecated Thick Client and Web Client. But one of the biggest annoyances with the vSphere Client is the default Session Timeout value of 120 minutes. It seems like I’m constantly re-authenticating. Good news, this can be easily changed from the vCenter Appliance Shell.

Windows Server network Unidentified (Public/Private) when multiple NICs present

Updated February 11, 2019: I was able to resolve the issue by setting the Cisco switch port configurations to an Edge Port. I’ve updated the post with the final solution.  

I was struggling to identify an issue where Windows Server would boot with an Unidentified, Public, or Private rather than the appropriate Domain network type. This caused the Windows Firewall to kick in blocking my RDP access. Restarting the Network Location Awareness service or cycling one of the Network Adapters would resolve the issue. But the root cause was a mystery until just recently…  (more…)


How to forward all WordPress pages from HTTP to HTTPS

Redirecting a WordPress website from HTTP to HTTPS is not as easy as it should be. I have yet to understand why there isn’t a simple checkbox to complete this task. There’s also numerous references which provide inaccurate information of how to accomplish this task. I’ll explain how to accomplish this with Apache, Nginx, IIS, as well as some popular web hosting control panels. These configuration changes are not WordPress-specific and can be referenced for any type of website. 

If you don’t already have a certificate, check out Let’s Encrypt to obtain a trusted certificate at no cost. In most cases Let’s Encrypt certificates can be easily requested from your CPanel or Plesk web hosting control panel.

Microsoft Account password out of sync when using Remote Desktop (RDP)

There’s an issue in Windows 10 which causes Microsoft Account passwords to become out of sync when using Remote Desktop (RDP). For example, I have a few computer systems running Windows 10 which I only access via Remote Desktop using my Microsoft Account (for example, username@outlook.com). If I were to change my Microsoft Account password from another computer system or Outlook.com, the new password will not work when connecting over RDP. However, the old password will continue to authenticate successfully. This is both annoying and a security issue. Below is a method to force a password sync.  (more…)


How to enable c$ admin share on Windows 10 and Server 2016

The hidden administrative network share (also known as c$ admin share) is not accessible by default in Windows 10. The administrative share is automatically created but can’t be access by browsing to “\\computername\c$” from a machine on a workgroup or home network. In a domain environment the c$ share should already be available. In a workstation or home environment the administrative share can be enabled from the registry.  (more…)
