About a year ago John Howard published guidance on how to get Hyper-V Manager to connect to Hyper-V servers over VPN. His network monitoring and suggestion to change the VPN connection IP settings so that the VPN adapter registers the machine’s new address in DHCP/DNS went a long way towards fixing the issue for me – however, we recently uncovered a couple of caveats as detailed in the comments on his original post.

I generally don’t do anything front-end if I can help it, but I’ll get my hands dirty when I need to. I recently played with a number of different K2 stylesheets and the newer Thematic framework while redesigning this site. I could only find one child theme that I really liked for Thematic, which was Second to None, but I wanted a dark version, so I set to work trying to interpret his stylesheet and inverted all of the background and text colours (as a starting point). This probably sounds easier than it is with the complexity of stylesheets today. At any rate, I eventually gave up when I realised that all of the icons looked funny in this inverted scheme, but I thought I’d share the Hex Colour picking tool that I found when bumbling through this, as I would have been lost with out it.
Working with software developers, I’ve probably seen SelfSSL used more often than in most lines of work, and also misuse of it. The purpose of this article is to draw some boxes around the different areas that come in to play when a site is self-certified.
Most obviously, the user requests the page through the browser, but the browser also warns of Certificate/DNS name mismatches. Unless the certificate was issued to the address through which the site is being browsed, the browser will produce certification warnings. This behaviour is expected and desirable as part of browser security. Continue reading “The stuff around SelfSSL”
Or… why it’s important to disable Host Time Synchronisation on a domain controller.
A few months ago I reminded myself of a major gotcha when planning a virtual infrastructure. Assume that you run more than one domain in more than one forest and that trusts are in place to authenticate users across those forests. This could be a development/test/staging environment, or as will no doubt be more common in the coming years, it could be a virtualised infrastructure.

It would appear that my grand idea to start my blog with EHLO world has already been pipped by many, but I can at least confirm that my blog title has achieved Google uniqueness, presumably according to its dubious etymology.
So what’s this all about? Windows stuff in the first instance, with a special focus on SharePoint, as I’m an Infrastructure Consultant for a leading British Microsoft Gold Partner specialising in SharePoint Products and Technologies. I’ve been working with SharePoint since pre-release WSS2/SPS2003. I cut my teeth on SharePoint concurrent with my growth from Technical Support Manager to Head of IT Infrastructure for another British Microsoft Gold Partner. Since then I’ve moved in to Infrastructure Architecture and consultancy. I anticipate this blog will focus on Windows, SharePoint, virtualisation, WAN technologies, authentication and whatever else I may stumble upon.
