No static entries on DC3
The mystrious software is listed in Add/Remove programs as 2.05.05. Spyware and AV scans did not pick it up. It has no install location or anything. Due to that I think it is still some type of spyware. Has a recyling bin icon next to it. Not installed on any other DC. However it was installed prior to installation in production enviroment, at out sourcing company's office. No one at the out sourcing company knows how it was setup. The person who set up DC3 is no long there.
Essentials can do agentless monitoring. Might need a license for each server though.
