When i got up in the morning today, i found nearly 30 dos-windows open on my PC. Each displaying the same error message: Pinging 126.96.36.199 with 64000 bytes of data: Reply from 188.8.131.52: TTL expired in transit. Request timed out. Request timed out. Request timed out. Request timed out. Request timed out. and also there were nearly 30 Windows Help, Pop-up dialog boxes, each showing the message: Cannot find /n/fh ping file. Do you want to try to find this yourself. YES or NO
Can't believe just to close all these dos windows, and dialog boxes it took me 10 minutes. What should i do to avoid this auto-popping up of dos windows and dialog boxes??? Ping localhost is working just fine. And also i am able to use my cable modem as usual, no problem with that. But when i type ping 184.108.40.206 , at command prompt, it says request timed out. How should i avoid this auto-popping up of dos-windows and dialog boxes??? NOTE: I have weblogic and websphere on my windows 2000 PC and i created a desktop shortcut icon for connecting to localhost websphere server. And later deleted this shortcut. Do you think this is causing the problem? can someone help me in trouble shooting this? Also why does this happen only in the night time? thanks, sri [ December 03, 2002: Message edited by: Sri Addanki ]

Here is an article on DOS attacks. Well, I am not sure is this a DOS thing for sure. Also, you didnt mention anything about the network that your computer is on, like company network, firewall, etc etc. If you are responsible for firewall, and such stuff for this machine, I would suggest you to install and configure a decent anti-virus tool, a firewall, some spy-ware removers like Ad-aware etc. Also, when you are connected to internet, if you close all browser sessions, IMs, File Share Utilities etc and try netstat -a on a command prompt, you can see if any suspicious program is trying to connect outside your machine with out your knowledge. Hope this helps, Ashok.
Couldn't you have went to the task manager and closed them all at the same time?

Hi Ashok, Thanks for the info again. I read that DOS article, i don't think thats the problem. This is a PC, and i'm connecting to internet through cable modem from my home computer. As u said, i ran netstat -a command and here's the output: But what does this mean?

Hi Paul, Thanks, but my TaskManager is not allowing me to do that, in the sense a typical dialogbox pops-up saying, some process is not responding.... thanks, sri
