We have a corporate network and when any user tries to download a pdf file from a specific site i will fail about 95% of the times.The site is www.mineduc.cl. I've been monitoring the firewall using ASDM and filtering mi ip address and i got the following:
5 Feb 22 2012 15:21:30 304001 10.120.0.76 Accessed URL 163.247.44.126:/descargar.php?id_doc=201102031230230

The ip address 10.120.0.76 is from my computer and 163.247.44.126 is the remote site's address. I've tested the connection using my connection from home and it works perfect 100% of the times so I know it has to be an issue in our firewall.
I'm not the network adminitrator but i'm helping trying to find the solution for this issue. Any help will be apreciated.
Regards, Felipe
