"the thing about the dods tracking capabilities" is true. They know what's up there, down to lost tool bags.

The instances you're thinking of are either "lost" as in "presumed dead" (like IMAGE) or non-Earth orbit probes (like ISEE-3). IMAGE was never untracked, and ISEE-3 was never supposed to be tracked (but its location was still known.)
