Not really. You'll get an answer in just about 8.44 years.

Yeah, that would mean that all the directory scanning would be local
rather than remote. Probably a lot faster that way.

Because that's the only way to specify the logon credentials for the
remote system. (Obviously, the server's local system account doesn't
have permission to access files on a remote system.)

There are other AT jobs running, of course...

Not sure how you figure that out, but hey.
Robocopy can't copy a file, it says "I can't copy this file" and exits.
Now the script has to do something about this.

Well, the mission was /designed/ to cover the solar system only, so the
transmission system was laid out to fit the bill at the lowest weight
possible.
It wasn't even designed to last that long, and only technological
advancements in receiver technology have made it possible to keep
contact over so many decades.

Note that the emission of a star is a constant signal to a good degree,
which probably helps.

I believe this is correct; I'd heard at one point that AD was based on
JET and also derived from Exchange (most directory services are at some
point derived from technology in mail systems - Novell's eDir product
uses the same database engine that GroupWise does, and GW has used
versions of that going back to WordPerfect Office).

OIC, yeah, that's true. It's a pretty small window of opportunity in
most cases, but yes, that circumstance could happen.

That's what insurance is for.

Mortgages tend to be amortized over a 15 or 30 year period, at least over
here. Ours is about $1500/month.

That doesn't mean that they never pay out, though. In cases of
catastropic events, they're required by law to pay out.
If they never paid out, then people wouldn't buy insurance.

Sure it does - a good workout causes adrenaline to start flowing, and
adrenaline produces a euphoric effect.
