Windows Server – Disable ‘Defender’

KB ID 0001710 Problem I got a call last night to help out a colleague, this involved using a ‘dubious’ piece of software that is very old, (I wont elaborate further). But to run it on a modern Windows Server is nearly impossible. The host detects the software as being infected (It may well be, but I’ve never suffered). So I need to keep the software in a password protected Zip file. And only extract it on a Virtual...

Hard Drive Full?

KB ID 0000012 Problem The fact that I’m going back to re-write article 0000012, should tell you this is an omnipresent problem! Either very suddenly, or slowly over time you have a drive or a volume that’s full to bursting point. These days with laptops which have smaller SSD drives it’s a common problem.

Windows Server: Disabling SSL 3.0, TLS 1.0, and TLS 1.1

KB ID 0001675 What are these protocols? Both SSL and TLS are cryptographic protocols designed to secure communications over a network (remember the internet is just a network). Originally we had SSL version 1 and version 2. But they were, (to be honest) ‘a bit bobbins’ and full of security holes, so never really took off. Version 3 however did and was widely supported. The problem with version 3 was, (again) that was also ‘bobbins’....

Get Ready for LDAPS Channel Binding

KB ID 0001645 Problem I have written about Enabling LDAPS a long time ago, but it’s a subject that’s about to become important again, so I’ll revisit the subject. Microsoft are about to ‘enforce’ LDAPS authentication against their domain controllers, in the March 2020 round of updates. Now delayed until second half of 2020. What does that mean? Well lookups against LDAP will now need to be secure, (i.e....

Windows Server – Change Your Password in an RDP Session (Send Ctrl+Alt+Del)

KB ID 0001183  Problem Colleague: Windows Server, Where’s Windows Security gone? Me: Eh? Colleague: Windows Security! Me: What are you trying to do? Colleague: I want to change my password and I can’t send a Ctrl+Alt+Delete to the remote server. Well I know that pressing Crtl+Alt+Delete would let you change your password like so; I wasn’t aware that in Server 2008 and earlier if you were connected via RDP you got a...
