Downloading from apache 2.0.48...

I have an apache server on my intranet, and want other users to be
able to download files from my server (my server is accessible from
other computers - checked).

I'm running apache 2.0.48 under WinXP. Everything worked fine under
apache 1.3.26.

The server itself works ok, most pages are served (from other comps
too), but there's a problem with some of the largest pages in the
manual too (when I try to open core.html from the manual - localy - it
doesn't open the entire file, so I guess there's a limit somewhere,
but I can't find it anywhere in the config files)...

When trying to download somethig from my server the download ends at
about 12 KB. I haven't noticed any error messages in the logs, saying
that something's wrong...
Can anyone help?
