Being on the leading edge of any technology can be exciting, but it’s often frustrating and even costly. There is an inherent risk associated with adopting technology that is new. Lack of community support or documentation if something goes wrong are just a couple of the issues that can arise. However, there are benefits to being an early adopter. For example, working hands-on with a new technology is the best way to understand how it works. As technology consultants, we view it as our job to understand what’s coming so we can advise our clients with a clear eye to the future.
A client asked us about alternatives to their current Remote Desktop Services (RDS) implementation which was being hosted by a third-party vendor. There were a few issues with their current setup, namely cost and maintaining multiple logins, and they didn’t have any type of domain or user directory. After exploring a few different RDS deployment scenarios, they ultimately decided on using a preview version of Azure Active Directory Domain Services (AD DS) on Azure virtual machines.
They really liked the idea of using Azure AD DS because of the promised benefits; no servers (on-premises or in the cloud) to maintain, simplified user interface, etc. We shared our assessment of the risks and unknowns of using an untested technology, but the client whole heartedly accepted these risks because there were so many more upsides to using Azure AD DS for their specific setup. So, we set out to implement Remote Desktop Services using Azure Active Directory Domain Services…and we learned a couple of things along the way which we are happy to share with you.
The first lesson learned was that with Azure AD DS, you cannot be added as a Domain Admin or Global Admin. They have their own security group called AAD DC Administrators that you have to create yourself. A good thing to note when dealing with Azure AD DS. Which lead us right to our second lesson learned.
When trying to add the Licensing Manager as a member of the AD group Terminal Server License Servers group, a permissions error popped up:
The computer account for license server [ServerName] cannot be added to the Terminal Server License Servers group in Active Directory Domain Services (AD DS) because of insufficient privileges.
Thinking back to that security group, I thought, “I am not a Domain Admin, I cannot be a Domain Admin.” I felt a little helpless. Thankfully the computer didn’t need to be added to the group since all RDS servers were on the same domain. But still, I couldn’t help feeling like something might be a miss later.
As a Microsoft partner we have top tier access to Microsoft support, who recommended a few solutions to this issue…which resulted in the same permissions’ roadblock.
When the Microsoft support engineer mentioned this was the first he has heard of someone trying this, I thought, I must be a pioneer attempting this while AD S was still in beta. But one thing was for sure, the Azure AD DS team liked the idea that someone was trying out an RDS implementation with it.
When you work with a beta version or when you install something without waiting for Service Pack 2 to be released you are blazing a new trail. When you do something new there is a thrill of being the first person to try something, and a long-standing honor in the tech world to be the first to figure something out.
In the end, after another hiccup or two, the rest of the Remote Desktop Services deployment went well, without any additional permission issues. And the result showed us that Remote Desktop Services does work well with Azure Active Directory Domain Services and was able to accomplish the client’s goals.
Once the beta for Azure Active Directory Domain Services is complete, I’m wondering if RDS will be on the list of supported technologies. Then I will feel like a true trailblazer cutting a path for others to follow.
Our experience with Microsoft tools gives us an inside track and an ability to work with these new technologies because we deeply understand the underlying platform. While being on the bleeding edge of technology can be risky, having experts to help guide you, navigate any issues and provide needed support can help mitigate some of these risks. And in the end, the benefits to your organization will outweigh any roadblocks encountered along the way.
