MAP 8.5 reporting old computer information

Question

We have been running map at regular intervals during our refresh process. One of the things we notices is that if we replace a computer with a new one and give it the same computer name( this is done for app specific reasons), when we rerun map it show
the machine but with stale data. For example: Machine A is Windows XP, we replace it with Machine B with Windows 7, but give it the same computer name. When we rerun Map the machine appears, but with the original machines IP address and OS information. This
is leasing to an inflated machine count. Could this be DNS related?

Answer 1

The MAP database is cumulative, but it will not overwrite data it has already collected. Each inventory scenario has a data set associated with it, and there is a lot of overlap between scenarios. When a scenario is selected, MAP expects to collect the data
in that data set. Once MAP has collected a piece of data from that data set from a computer, it does not query that computer for that data again. If all of the expected data is collected, then MAP will skip that computer in subsequent inventory runs.
If you were to choose a different inventory scenario that overlaps with the first scenario, but it also has data not previously collected, MAP will try those new queries on all current and previously discovered machines, but it will skip any queries that
are part of the overlap and had been collected successfully in previous runs. MAP tracks these data points on a computer by computer basis. There is no way to “refresh” the data. If something in the environment changes, the only way to pick that up is to create
a new database within MAP (File > Select databases) and run a new scan.
