Document not saved error

I've read the online doco regarding the "document not
saved" error, but it all implies you can save to an alt
location. I can't. When the error comes up for me, I
can't save to neither network nor locel drives. I've had
this happen on 2 different machine, so it's not my
network card.

My office neighbor has seen this too, so it could
possibly imply a truck on our LAN might be failing? But
still, why couldn't I saveas locally?

Help please.
