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:

The network bridge on device ‘VMnet0’ is not running. The virtual machine will not be able to communicate with the host or with other machines on your network. Failed to connect virtual device ‘Ethernet0’.

the network bridge on device vmnet0 is not running failed to connect to virtual device ethernet0 Continue reading

Exchange 2010 SP3 Update Rollup 13 released and installation tips

Microsoft Exchange 2010 SP3 Update Rollup 11 Installtion tips

It been a busy couple of months with two Exchange migrations, one from SBS 2008 to Exchange 2013 and another from Exchange 2010 to Exchange 2016 so this post is a little late coming!

On 14th March Microsoft released the Exchange 2010 SP3 Update Rollup 13.

I installed Update Rollup 13 on my test SBS 2011 server this evening and it took just 9 minutes from start to finish, so I wouldn’t expect it to take much longer than this in production.

The new update was released today so please test before installing into your production environment. Maybe even wait a few days or a week or two to make sure the QA is up to scratch on it.

For migrations to Exchange 2016, Exchange 2010 SP3 Update Rollup 11 is the minimum version that will be supported in a coexistance environment.

Exchange 2013 Initial Configuration Settings: How to configure virtual directories (Part 10)

Exchange 2013 logo

In part 10 of this mini-series, I’ll look at how to configure the virtual directories used by Exchange 2013. We’ll need to configure these to match the FQDNs we request on our SSL certificate.

It’s assumed that split-brain DNS will be setup for the configuration to work. The essenace of split-brain DNS is that your external domain name is also configured on your internal DNS servers, but the A records on the internal DNS server point to the internal IP address of the server whereas the domain name configured on your external DNS servers point to the external IP address of your server. So whether a client is internal or external the FQDN will always resolve to the correct IP address.

We’ll be configuring the following services:

  • Autodiscover
  • Exchange Admin  Center (ecp)
  • Outlook Web App (owa)
  • Exchange Web Services (EWS)
  • Active Sync
  • Offline Address Book (OAB)
  • Outlook Anywhere

Exchange 2013 Initial Configuration Settings: How to change the FQDN on the Default Frontend receive connector (Part 9)

Exchange 2013 logo

In part 9 of this mini-series, I’ll look at how to configure the Fully Qualified Domain Name (FQDN) of the Default Frontend receive connector in Exchange 2013.

Firstly a warning: Don’t modify the FQDN value on the default Receive connector Default that’s automatically created on Mailbox servers. If you have multiple Mailbox servers in your Exchange organization and you change the FQDN value on the Default Receive connector, internal mail flow between Mailbox servers fails.

In a single Mailbox server environment to change the Default Frontend receive connector FQDN follow the steps below.
