If you see the error "Cannot find path for destination inbox Asset Intelligence KB Manager on server REGISTRY" on a secondary site server in the mpfdm.log you are missing some registry kes that point to this inbox. This is a known issue and you need to manually create a couple registry keys and the directories that are missing. The easiest way to know exactly what to ccreate is to look at a server that does not have the error and essentially copy the keys from it. You can't do export and import though because the keys are server specific. The will be located in two places First of all create a new string value under HKLM\Software\Microsoft\SMS\MPFDM\Inboes. Name this key "Asset Intelligence KB Manager" and for the value enter the path to that directory for example C:\SMS\inboxes\amtproxymgr.box. Next you will need to create a key under HKLM\Software\Microsoft\SMS\Inbox Source\Inbox Definitions\ look for the key with the largest numeric value here and name your new key the next largest numeric value.
I advise that anyone following these instructions backup the registry first and also test this in a lab if at all possible!
Enter the information in the key as follows:
new string value "Inbox Name" with value of "Asset Intelligence KB Manager"
new string value "Relative Path" with value of "inboxes\AIKbMgr.box"
new string value of "NAL Path" with no value entered
new DWord value User Rights hex = 0
new DWord value Service Rights hex = 4
new DWord value Monitoring Enabled hex = 1
new DWord value Location Type hex = 1
new DWord value Guest Rights hex = 1
