I was browsing through some tables and noticed something in tblComputers. LastKnownIP seems to be blank in some instances. The only reason I can think of is that we have several computers that had their onboard network card burnout and had to place a secondary NIC in. Is LS just picking up on the first NIC it sees and using that for the IP? If so, could you place a check in to make sure the NIC is enabled, and if it isn't to move on to the next?
