This clearly means that there must be something that was changed on my customer’s environment.Īfter asking a bunch of questions, it appears that they have upgraded their server operating system from Windows Server 2003 to Windows Server 2008 R2. So I did a quick check but couldn’t find anything that has changed on my MacBook Pro (it simply means that I rely so much on VMs that my host machines – whether PC or Macs – don’t get changed that often.) What’s even more frustrating is that it works on one environment but not on another. I was under the impression that there must be something that changed on my system. This used to work on one of their environments but now it doesn’t. I was testing out my connectivity to some of my customers’ network using Remote Desktop Connection on my MacBook Pro. Have you ever wondered why your Remote Desktop Connection on your Mac works well on one system but not on another?
