Can A Domain Trust Another Domain With The Same ‘Root Domain’ Name?

KB ID 0001288  Problem About a month ago I was with a client to do some investigation/consultancy, they were a large company with their head office in the UK and a number of other offices around the world. They had a number of domains and sub domains and wanted to consolidate them all into a new domain. Well that’s all OK, but the UK company has been purchased by a large American company, who were putting a lot of pressure on...

Cisco FirePOWER is Blocking an Application

KB ID 0001286  Problem A few weeks ago I installed a 5525-X firewall for a client, and set it up as follows; ASA Setup FirePOWER Services (for ASDM) And all was well, then a week later I got an email… One of our teachers is doing a project with MATHS and ICT involving bitcoin. Basically, he has something called BITCOIN CORE WALLET installed and it used to work with the old Firewall. I’ve installed it on my work laptop and taken...

Avaya / Nortel Switch Notes

KB ID 0001285  Problem I don’t often use Nortel (now Avaya) switches, I know they are decent, but in my day job I usually work on Cisco, occasionally HP, and other cheap assorted nastiness switches. I was replacing an old 10/100 Cisco 3750 switch with a Nortel 4526GTX this week, and thought I’d take some notes for the common things I do, just in case I have to do another. So this post is an eclectic collection of the...

Changing the Windows 10 Browser, So It Isn’t Edge

KB ID 0001284 Problem I’ve seen one person use Edge as their browser in a business environment. I’ve got nothing against it, (I use a macOSX anyway). But I had a client that asked me how to make sure his machines are set to NOT use Edge as the default browser. I’m going to use Internet Explorer instead, but you can do the same with Chrome or Firefox depending on your browser of choice. Solution What I’m going...

Stop Windows Servers ‘Locking’ with Group Policy

KB ID 0001283  Problem Servers locking themselves after a period of inactivity is, (in most cases) a good thing. But on my test network that only I use it gets a bit annoying switching between machines and constantly having to unlock Windows all the time!   Note: For obvious security reasons don’t do this on a production network! Solution   Create a new GPO linked to your computer OU, (or edit an existing one). Edit the policy....

Windows – Forcing Domain Group Policy

KB ID 0001282 Problem I’ve written hundreds of posts about doing things with group policies. Every time I finish one, I write a couple of paragraphs on how long to wait, or how to force the policy etc. So I’ve finally got round to writing a post I can simply reference! How Long Before Group Policy Changes Are Applied? This is something that hasn’t changed since I was doing Windows 2000 exams 🙂 The default interval...

Windows – Deploy and Configure Photo Screen Saver via GPO

Screen Saver via GPO KB ID 0001281 Problem I was tasked with working out how to do this for a client a couple of weeks ago, so I thought it would make a decent article. I’m going to have a central server share, with some photos in, then I’m going to copy them down to all the clients, and finally set their screen saver to use those photos as a ‘slide show’ screen saver. I’ve done this with Windows 10...

AnyConnect – “Connection attempt has failed due to server communication errors’

KB ID 0001279  Problem We had a firewall fail at work this week, as part of the rebuild the latest OS was put on it, version 9.7(1). I thought no more about it until I tried to VPN in and got this; I used my Windows 10 VM and that connected fine, only my MacBook could not connect, this VPN tunnel is a big deal I need it to get onto client’s networks. I tried my other VPN connections and every one was fine, only the recently...
