Hello all. I was hoping you could give me some help on this.

I have a huge file (Excel 2007 format, 9 sheets, at least 4 of which
have 4 columns by 100,000+ rows, Vlookups, if/thens, tons of stuff.
file size is over 25MB. HUGE.) saved on a network drive (required by
my work). About half of the time when I hit the "save" button, it
saves to what I must assume is a temp file, then copies that over to
the network drive ("Saving" progress bar, then a box which pops up and
has a progress bar and the word "Saving"), and then pops up a message
box with "Access denied. Contact your administrator.". My
administrator has no clue, except to say that it's probably excel
having some sort of issue saving to the network. The part that REALLY
bothers me is that it's only about half of the time. I could
understand if it were EVERY time, but can't figure out half.

Any ideas? Known bug, to be fixed in SP1?

Any help you could give would be wonderful. Thanks,
