The server doesn't shut down, it just kind of shuts everybody else down.
But your mention of TEMPDIR jostled some old memory cells awake, and
essentially answered the question. I do [did] a similar thing with
temporary directories as you discuss, just another directory location.
But that location (R_USER) disappeared when I upgraded (one or all of R
to 2 to 3, OS XP to 7, machine 34 to 62 bit). So R has to create a temp
dir by default. I think that default directory gets derailed during
network-wide system scans, thus Tuesdays and weekends for me.
Sys.getenv('R_USER')
[1] "C:\\Users\\fowlerm\\Documents"
> tempdir()
[1] "C:\\Users\\fowlerm\\AppData\\Local\\Temp\\1\\RtmpeqbLeR"

This is a different error than I thought you described. I thought
something had shut down the server, but it looks like something has
deleted your temporary directory. You might be able to tell your OS
not to do that (if it was the OS that did), or you can put your
temporary directory in a location that is less likely to get deleted,
e.g. by setting the TMPDIR environment variable to somewhere else before
you start R. For example, I typically run with TMPDIR set to C:/temp
when I'm debugging things.
