When running an enpoint discover scan the scan will run as the scan type "Full" instead of "Differential" even when the option "" is checked None
This is caused when there has not been a completed full scan. Often times this happens when a full scan can not be completed all of the way because some of the clients do not check in before the time out or one of the clients is permenantly offline. In order for a full scan to occur there must be at least one succesful full scan.
There are three solutions to this issue.
1. Ensure that all of the clients are online for the scan and remove any offline agents. This solution is usually only feasable for smaller installs with fewer clients.
2. Upgrade to DLP 15. In DLP 15 there is a targeting option that will allow you to target fewer agents which will allow for a small enough target which can ensure a full scan completes on all of the targeted agents. Once there has been a full scan then all of the other agents can be added to the scan and differential scans will occur as expected from agents that have had a full scan.
3. If removing inactive clients from the console and upgrading to DLP 15 are not options then you can use the following steps to workaround the issue.
