Enable Remote Desktop using CMD

To enable remote desktop.
• Open registry editor by running regedit from Run.
• Go to the node HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server
• Change the data of the value fDenyTSConnections to 0.
We can enable remote desktop from windows command line by running the following command.
reg add “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server” /v fDenyTSConnections /t REG_DWORD /d 0 /f
To disable remote desktop we need to run the below command.
reg add “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server” /v fDenyTSConnections /t REG_DWORD /d 1 /f
Reboot or logoff is not required after running the above command. I have tested this on Windows XP and Windows 7 and it has worked fine. It would work fine on Windows Vista too.

Quickly find AD user password expiration date

Knowing when a password should expire is sometimes useful information.
To find out all users password expiration date, open up powershell on the DC and run:

Get-ADUser -filter {Enabled -eq $True -and PasswordNeverExpires -eq $False} –Properties “DisplayName”, “msDS-UserPasswordExpiryTimeComputed” | Select-Object -Property “Displayname”,@{Name=”ExpiryDate”;Expression={[datetime]::FromFileTime($_.”msDS-UserPasswordExpiryTimeComputed”)}}

It will output for you a human readable list such as in the above post screenshot.
I have tested and can confirm that the above script is working on Server 2008, 2008 R2, 2012, 2012 R2, 2016 & 2019.

WPBakery Page Builder not working in chrome and shows console errors

Just a quick one, hoping it will help someone,

If you have a wordpress site with WPBakery Page Builder running on it, and find the frontend builder is not working, and if you also happen to use cloudflare – Rocket Loader™ is your issue.

Go to cloudflare and under speed –> Optimization –> turn off Rocket Loader™

Go back to WordPress and within a few mins, or the time your cache takes to update – your visual composer/WPBakery Page Builder will be working again.

Force Active Directory replication on a domain controller

To force Active Directory replication, on the server which needs forced to update, run using elevated CMD:

repadmin /syncall /AeD

A = All Partitions
e = Cross Site (Enterprise)
D = Show server name in output.

This will initiate a pull replication.

OR if you are already on on your main DC, and need to update any other servers in the AD, you can do a push replication:

repadmin /syncall /APeD

A = All Partitions
e = Cross Site (Enterprise)
D = Show server name in output.
P = Push

The technet article with further info can be found here:

https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-r2-and-2012/cc770963(v=ws.11)

Perhaps, you like me are trying to move away from the old CMD comandlines, and migrate into PowerShell – if that is the case, bad news -currently there is no update alternative for repadmin in powershell – the Get-ADReplication commands are great for troubleshooting but offer no easy interface for updating AD.

Remote Web Workspace not working [Solved]

Remote Web Workspace breaks. Alot.

In all versions of SBS (now end of life) Microsoft graced us with the ability for remote users to remote into the server to then hop accross to their own PC’s via RDP.

This was great in theory, and worked for a while, until updated servers broke this feature. The root cause was an update to .net framework, starting at version 4.5.1 which included memory checking to make sure you have at least 5% free memory.

Ok, so why the issues. Well anyone who knows Exchange, knows that the information store will use as much free memory as possible – which in turn often caused the Remote desktop Gateway service to crash, due to not having 5% free memory.

Here is the quick fix if you only have 5 mins;

– Restart the MS Exchange information store,
– Then restart/start the Remote Desktop Gateway Service

Here is the proper fix:

– Run adsiedit.msc
– Connect to: Select a well known Naming Context : [Configuration]
– Expand the following:
Configuration\Services\Microsoft Exchange\ (First Organization) \Administrative Groups\ (Exchange Administrative Group) \Servers\ (Server Name)
– Right click on CN=Information Store and click properties
– Update the values of msExchESEParamCacheSizeMin and msExchESEParamCacheSizeMax to something below 94% of your servers max ram capacity – i is in KB’s divided by a 32byte page so…

Basic maths is ==> Target Cache Size in GB = (# * 1024 * 1024) / 32

There is an excellent table over at meridian.ws which is much easier than doing the maths:
