Automated checking of external IP

You host your own mailserver (and the provider even lets you), but the external IP address of your DSL/Cable connection is dynamic. So after a few days suddenly you realise there is no connection to the mailserver, and all the mail is bounced back to the senders.

Testing Exchange connectivity

Nowadays everyone wants to be able to sync their phone with email and calendars. Ofcourse you have to provide this on the widely used Windows Small Business Server or normal Exchange Servers as well.

Lucky for admins it is still possible to use the command line for tasks that just take up a lot of our time when doing it via the GUI. There are also some tips for Linux in here for good measure, but lets face it, as long as Windows is used in 90% of all businesses we are pretty much stuck with these tedious tasks.

New tech blog

Hello friends and random strangers. To keep track of some handy tools and settings in my work field I’ve decided to make a blog. On this blog you wont find any whimsical stories about my life or anything like that and it won’t be updated that often most likely. I just use this to keep track of some technical solutions I’ve had dealings with and keep anyone who is interested informed. Also from time to time I will post some general tips about IT/computer related subjects that might interest computer users, most of these will be software tips and extensions for my favorite browser which is Chrome at the moment.
