Page Not Found / Timer_EntityBody Issue

by Otto on February 27, 2007

I have a classic ASP web site that I just moved to a Windows 2003 / IIS6 server.  The application uses SSL.  I have a user who is getting “Page Not Found” errors.  I have had them turn off Friendly Error Messages in Internet Explorer 7 and instead of getting the “Page Not Found” error, they get a blank page.

There are no errors being thrown in my Event Logs, but when I check my IIS logs, I see this in the httperr1.log log file:

2007-02-26 23:47:59 x.x.x.x 15124 x.x.x.x 443 HTTP/1.1 POST /default.asp – 628354416 Timer_EntityBody ClassicASP

I’ve removed the IP address of both the client and server.  It appears that the issue has something to do with Timer_EntityBody.

I found this Microsoft KB: – this client isn’t running IIS on his computer, nor is this an ASP.NET application.

A post on Expert Exchange (registration required), someone mentions the MTU-Value for the network.

The client has two different Internet connections coming into his office.  When he uses his fractional T1, he doesn’t experience any errors with my site.  When he uses his Comcast broadband connection, he gets the errors.

I have had him run the following commands on both his networks:

for /l %a in (100,1,1500) do ping x.x.x.x -n 1 -i 250 -l %a >> MTUTest-Comcast.txt
for /l %a in (100,1,1500) do ping x.x.x.x -n 1 -i 250 -l %a >> MTUTest-T1.txt

This pings my server increasing the packet size from 100 to 1500.  When the packet size is around 1470, we start seeing packet loss on both connections.

I have him run the following commands on both connections:

ping x.x.x.x -n 20 -l 1473 -w 2500 >> MTUTest-2-Comcast.txt
ping x.x.x.x -n 20 -l 1473 -w 2500 >> MTUTest-2-T1.txt

He sent me the results and we had 100% packet loss.  Thinking something was not right, I had him run the commands again and the results were the same, 100% packet loss.

Is there a way to resolve this issue?  Why am I seeing the errors now with Windows 2003 / IIS 6 and we didn’t have this problem under Windows 2000 / IIS5?

Wonder if blogs will help me find the answer faster then the forums will?
