Top 10 Blog posts of 2017

Happy New Year!

In 2017 the OxfordSBSGuy.com blog has gone from strength to strength, with 26 posts and 863,000 views. In 2017 I implemented SSL and been working on some tweaks here and there to improve performance.  This year I’m considering a redesign and new hosting is in the pipeline to improve performance further. Thank you for your support.

Below are the top ten articles in 2017

Below is a snapshot of the current versions as of 24 December 2017.

How to resolve VMware Workstation “The network bridge on device ‘VMnet0’ is not running”

VMware

So I turned on my test SBS 2011 server today to test out the latest Exchange Update Rollup and was greeted by an VM  that was hanging on startup. Looking into the issue more closely the virtual network adapter was disconnected and when I tried to select ‘connect’ I received the following error message:
