Not being able to access a particular website

I am not being able to access one website: http://www.soph.uab.edu/index.asp?ID=2
from my computer.

I can access all other websites from my computer, and I can access this website from other computers without any problem.

I am running a Dell Inspiron 8500 with P4 and 256 MB RAM, with Win XP Professional and use IE6 as my browser.

Please help !!
Thanks,

I had the same issue with my own web host and ebay,

I assume you are adsl and using a router if so the following will apply if not it may be your ISP.

Unless otherwise set, windows defaults MTU to 1500, or a lower value of 576 for external networks. 1500 is ok unless you are running PPPoE, or want to use IPSec (Secure VPNs), or both, (it is then too big). 576 is not efficient
for the broadband/internet, (it is too small).

Finding the largest MTU, by EXPERIMENT
If your MTU is too low already, (maybe 576), the following method will not be able to detect whether you can switch to an optimal size..... So first follow "CHANGING MTU for PPPoE" to reset MTU to 1500, reboot, then try the site again

I am running 1510
