Had a problem recently with SharePoint 2010 when we changed our main way of accessing the site to a public domain name. This change made all Office Applications 2007 and 2010 request authentication when opening and saving to or from SharePoint.
After a longer research into the issue I found this Microsoft KB.
In there Microsoft informs about how WebDav secures sites or networks. I always knew that SharePoint uses WebDav to share documents to Office applications however I had no idea that you had to specify a trusted location if it uses an Internet FQDN instead of a local netbios name.
So I followed the KB and I actually deloyed the registry key via Group Policy Prefferences and after people restarted their PCs no more calls about having to authenticate.
Was configuring some Dell 2824 switches which are pretty good switches for the money. However I ran into some issues.
The command line over the serial connection didn't allow me to set the IP or anything so I did a quick Google and came across this article.
In there I found that the 28xx series switches use a default IP of 192.168.2.1. I browsed there and was able to login with admin and no password. This allowed me to fully set them up.
I hope that this helps somebody else too.
