Both Johan Arwidmark and Mikael Nystrom have been writing extensively as of late regarding Monitoring in MDT, one of the coolest features added in the 2012 release. Monitoring allows IT admins to keep an eye on deployments from not just a centralized location, but any system with MDT installed and an active connection to the deployment share. More importantly, one of the neatest features on top of just monitoring is that we can then start remote desktop sessions of these deployed systems after the deployment is complete, but MDT by default will only show deployments from the last three days, which makes this a little hard to do after the fact once just a few days have passed. However, after reading one of Johan’s latest posts on this topic, it turns out this can be changed by making a simple modification to one configuration file.
Changing the default time MDT remembers deployed systems in the monitoring tab is quite easy.
Find and edit the following file:
c:\Program Files\Microsoft Deployment Toolkit\Monitor\Microsoft.BDD.MonitorService.exe.config
Note, the database this all relies on has size limits, so if this begins to cause problems after deploying a large amount of systems, take this down a notch, but notice the default max is 1000 deploys. Just keep that in mind.
