Server 2012 RDS Certificate Solution

Everything I had read online pointed to having a Public SAN certificate or using a Self-Signed certificate and pushing it out via group policy. I could not find anything about using an Enterprise CA to delve out a certificate for RDS. This got me thinking about using a SAN certificate internally, but how?

On your Enterprise CA you can run the following commands to allow for SAN Certs
certutil -setreg policy\EditFlags +EDITF_ATTRIBUTESUBJECTALTNAME2
net stop certsvc
net start certsvc

Next lets open the Certificates Templates Console
Right-Click the Computer certificate and click “Duplicate Template”.


I just called this template RDS-Cert and set the Validity period to 4 Years.

Fast – Inactive AD Computers List

One of easiest ways to get a current list of all the inactive Computers in your AD is by using DSQuery. Below you will find two examples of how I use this. You will notice the “-limit 0”. This allows the query to pull back an unlimited amount of computers. At the end I am piping this out to a csv file.

Computer accounts not used in the last 6 months/26 weeks.
dsquery computer -inactive 26 -limit 0 > List_6_months.csv

Computer accounts not used in the last 2 months/8 weeks.
dsquery computer -inactive 8 -limit 0 > List_2_Months.csv
