Server 2016, MDT 2013, W10 1809 6.3.8456.1000 SQL Compact Database

If you don't connect MDT on Server 2016 to an SQL Database it will use SQL Server Compact to store information

You see in MONITOR. You ONLY access the Info from the Compact Edition with SQL Management Studio 2008R2

And NOT the newer Version I have read somewhere. With the SQL Management Studio 2008R2 we

Can open the SDF database from C:\Program Files\Microsoft Deployment Toolkit\Monitor\MDT_Monitor.sdf

You can also access through API Web:

http://localhost:9801/MDTMonitorData

http://localhost:9801/MDTMonitorData/Computers

http://localhost:9801/MDTMonitorData/ComputerIdentities

It's written that they keep the information in there for 3 days. So this is only a temporary solution until the client runs.

C:\Program Files\Microsoft Deployment Toolkit\Monitor\MDT_Monitor.sdf

To see or view data itself you could use:
