DOS ain't dead

recursing subdirectories (Developers)

You're supposed to set the DTA to a different buffer ("different DTA") whenever (before) you open a new concurrent search. The find data in the first DTA should be sufficient to resume the first search, when you reset the DTA to point to that find data, regardless of how many other searches you started. Alternatively you could copy the find data from a single DTA and stash it elsewhere, then restore it later. In any case, the populated find data if preserved is supposed to be able to resume concurrent searches regardless of what order you call the DOS.

Redirectors should try to emulate this, although the find data may not be large enough to reference their file system internals. So the find data can contain a handle, pointing to a redirector-internal find data block, which is cleaned up either when the search call returns "no more files", LFN find close is called, or eg the process terminates.
