We have been using Web Help Desk for quite some time now, currently running 12.4.2. We have recently started ramping up our usage of the asset piece. Due to us not having SCCM or Lansweeper, we are using the WMI discovery and having multiple problems with it.
1 - Will not reliably detect all of our PCs. It is detecting probably 400 of the 450 PC's that we have, with no good reason why it is skipping the others.
2 - Bigger problem seems to be that it is overwriting information in assets. For example, if it scans IP 192.168.2.2 and finds asset with network name of PC-12345, we then enter hand keyed information about that PC and its owner in Assets. Then a month from now, it rescans 192.168.2.2 again, and because we are using DHCP, now the PC that has that IP is PC-56789, now it replaces the network name in that asset entry, but leaves all the previous hand keyed information in there. So we start getting incorrect information in our assets.
I guess my question is, is the IP address the unique identifier in the database that ties all other fields in the asset together? And if it is, how do you deal with DHCP and changing IP addresses?
