Problem:
Default Host Groups have 2 digit IDs (for example, 28, 30) but user created host groups have 5 digit IDs (for example, 50081). If a user deletes a default host group and then recreates it as a custom host group it has this larger ID # and some things can not work correctly because of this. For example, Host Classifier can not find the newly created host group because of the incorrect ID #. To fix this the ID # needs to match the default value.
Solution:
Import the Host Group
Import a host group with the correct ID can fix the problem. You can import this from a backup or export the host group from another system. If necessary, create a new domain on the system, export the desired host groups, and then delete the newly created domain.
Alternative Solution:
Edit the host-group id field to the correct value in the host_groups.xml (/lancope/var/smc/config/domain_<DOMAIN_ID>/host-groups.xml) can also correct the issue.
Note: There could be the need to reinstall the Host Classifier App after you fix the host group ID value for it to correctly pick up the fixed host groups.
