Find The Azure AD Join Type
KB ID 0001597 Problem I recently did a post about Joining Azure AD. while working on that I found out there were three different Azure AD ‘States’ (see below). But how do you pingd out your Azure AD Join Type? Azure AD Joined: Aimed at Corporate owned machines joined to Azure AD, (or CYOD devices). Azure AD Registered (Was called Workplace Joined, and still is if you work in PowerShell). Aimed at BYOD devices. Azure Hybrid...
Leave Domain: “A general network error occurred’
KB ID 0001738 Problem After a recent lab on the test bench, I ended up with a 2008 x32 standard server. It took me a while to get this setup and running, so I wanted to keep it (or turn it into a VMware template should I ever need another). But first I needed to ‘remove it’ from the domain it was in. However, when attempting to do so this happened; Computer Name /Domain Changes The following error occurred validating...
Domain Join SID Error
KB ID 0001732 Problem Thankfully I don’t see a SID error very often these days; The following error occurred when attempting to join the domain ‘{domain-name} The domain join cannot be completed because the SID of the domain you attempted to join was identical to the SID of this machine. This is a symptom of an improperly cloned operating system install. You should run Sysprep on this machine in order to generate a new...
Running Dropbox On Windows Server
KB ID 0001489 Problem If you are here, you have probably already found out that Dropbox is not supported on Windows Server platforms. You can install it and set it up happily but it stops working and needs to be relaunched all the time (manually). I love dropbox! So much I actually pay for it! I run it on my management server and its handy for copying file up into my test network, so I can appreciate how annoying it is having to...
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. I’ve seen literally hundreds of post in forums, most of them are answered with ‘Use...
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’....
DHCP Scope: Full of BAD_ADDRESS Entries
KB ID 0001651 Problem I had a client machine struggling to get an DHCP address, and when I looked in DHCP the scope it was full of this; BAD_ADDRESS This address Is Already in Use Solution A tour of Google and forums is full of posts by people with this problem, and other than, ‘Oh I looked in the logs and fixed it’ (with no mention of what log, or where this log was), or ‘Yeah I used Wireshark and located a problem...
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...
