FTP / wget / browser download through M$ proxy server. 32 bit issue?

[bruce.labitt at autoliv.com]

Since my blade server supplier has insisted, I need to install a different 
distro on the head node.  (Support and all that...  The blade is not 
running yet, so we want to back off to a "known" distro and 
configuration.) Once I get everything going again I think I will reinstall 
Ubuntu 64 bit since it seems to support newer hardware and applications - 
at least for the ones that I need.  Anyways, I have been trying to 
download the CentOS5.2 DVD iso.  Everything I have tried seems to fail in 
a peculiar fashion.  I think it may be the MS proxy server.

If I attempt to download thru the browser on either winxp (IE) or thru 
firefox3 on ubuntu I seem to get the same behavior.  If I download a file 
< 2^32 bytes = 4,294,967,296 bytes, I get success for both OS.  An example 
is the 32 bit version of CentOS5.2 = 4,020,600,382 bytes.

If I download the file that I need (64 bit CentOS = ~4,600,000,000 bytes) 
which is slightly greater than 2^32 bytes the download fails.  It fails 
after downloading 306,020,501 bytes = ~ 292MB.  This happens if I use the 
browser, or if I use wget on linux.  For wget I connect thru my proxy 
which then connects to the MS proxy.  This is done thru ntlmaps.

For my linux box browser, I use the automatic proxy configuration URL that 
my company uses, which is a WPAD.dat file, which is the same as used on my 
WinXP Pro 32bit laptop.

I would have used bit torrent (of some flavor) but that is blocked here. 
It is getting hard to find non-torrent DVD images.

Anyone see anything like this?  Is there a solution?  MS proxy change or 
update? 

Thanks
