Web Based Password Generator

Ok, so this is kind of a little thing I did. I wanted a page that would generate a password without anything done on the server side. I wanted it all to be done on the client. I also wanted the ability to exclude

WSUS/Server 2012R2 and HTTPS

I wanted to switch my WSUS implementation over to https. Because I like https and there is rarely ever a reason not to use it. So, I set up my bindings in IIS and setup my group policy to point to the correct URL.

VSO Build and File Select/Exclude

From Nuget.Server to NugetGallery

Windows 10 going to sleep to quickly

Well, I've had a very annoying issue that I've been fighting. I enabled wake-on-lan on my desktop and had it start going to sleep. This was great. Saves power and I can still remote into it. I installed the wake on lan tools on

Wake-on-lan, windows 10 and Linux

Team City, MSBuild, MSDeploy, Web Deploy, NTLM and aspnet_client

Ok, more on Team City and build/deploy stuff. In my previous blog post, I showed how to run team city as a domain user account. One of the reasons was for web deploy to not store the username/password in the configuration. There's

Install MS-DOS 6.22 from upgrade disks

OK, this was really dumb, but I wanted to install DOS, and only had access to the upgrade disks. Lame. I got the MS-DOS 6.22 floppies from my MSDN (yes it's still there). But, MSDN only has the upgrade disks. No install disks.
