I'm so mad at my computer I'm about to shake the hell out of something.

I can access www.sunysb.edu on my brother's computer that I take care of/configure, but can not access it on my computer. same router, same modem, both wired. No firewall except for Winxp sp1 firewall. Cleared out cache and lower all the internet option setting to minimal. No go.

Doesn't matter whether I use IE or firefox.

Traceroute times out after the 10th hop. But this shouldn't matter because I can access it on my bro's computer. WHAT CAN IT BE???? :brokenheart: Something is preventing my computer from accessing sunysb.edu. Has anyone faced similar complications? Can you please share your experience??

action canceled on IE

Timed out message on firefox

I wiped out the hosts file and still no go...

I read similar posts in dslreports and some other forums by searching through google. Most of the time it's the hosts file. I guess there is no other known solution except to reformat. bah

Did this start today? Do the traceroutes match up until the part where they cut off for you?

Bring up a command prompt and try the following
"nslookup www.sunysb.edu"
If that work, try
"telnet x.x.x.x 80" where x.x.x.x is the IP address you got.
See if you get a connection, if you do, the cmd window should go blank, try typing "GET /", it won't echo, just type it and press enter.

Dear lord, i just tried it on AOL and it works. Shoot me now. :D


n0cmonkey = been happening for a while now, but I always assumed that the server was down or something. Only today while running from computer to computer did I realize that mine was unable to access sunysb.edu


Sunner = nslookup a success

the telnet part is erratic. usually it fails

C:\Documents and Settings\lazee>telnet 129.49.2.176 80
Connecting To 129.49.2.176...Could not open connection to the host, on port 80:
Connect failed
Click to expand...


BUT when it succeeds... when i type get /
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<HTML><HEAD>
<TITLE>501 Method
Not Implemented</TITLE>
</HEAD><BODY>
<H1>Method Not Implemented</H1>
get to /index
.shtml not supported.<P>
Invalid method in request get /<P>
</BODY></HTML>


Connection to host lost.

501 is an error of some sort. You want a 200, IIRC. :p

Compare the traceroutes between the two machines. Compare the nslookup between the two machines. I think there are 2 hosts files on Windows machines, but darned if I know where they both are. :p

Maybe try installing opera.

I was thinking the same thing myself, so I ran a traceroute from the computer and from the dsl modem.

I'll be damned.

DSL MODEM

COMPUTER

For some reason my computer refuses to go from the Bethpage cablevision UBR to the Stony brook lightpath UBR. Damn. This is wierd.

Thank you guys for your suggestions and time. I guess, eventually I'll have to reformat and keep an eye on when I lose connection as I install/run things back.

And to think, I was just trying to waste your time while I came up with a better suggestion. :p

Just kidding of course. ;)

saw some adware the other day on a system that put a shitload of stuff in the hosts file, and pointed them all to 127.0.0.1 . Really wreaked havoc with our guys so they came to get me to take a look... at any rate, I'd make sure it looks normal.

Typing "GET /" is incorrect -- in the future type "GET / HTTP/1.0". The 501 error was complaining about your malformed request.

What kind of network/broadband connection do you have? Have you tried downloading "DRTCP", and changing the MTU on your NIC/interface to 1492 or lower?

With your router and software firewall in place, you may not be recieving the proper ICMP messages back, if the remote router or server is even sending them, that is.
