I have a problem, probably with my NIC. In general, the problem is that I DC from the Internet about every 1 sec to 5 min. A little more in-depth: I've got an ISR with 3 PCs connected through Ethernet. (Cable) Now, Only 1 PC have this problem. The ISR is constantly connected to the ISP and my connection to the ISR is intercepted. I have no idea why that happens but i have a few ways to reconnect: 1. Restart the PC - works 1/2 of the times. 2. Disable & then Enable The NIC - works 1/2 of the times. 3. Repair the NIC using Microsoft Repair function - works 1/10 of times. Symptom Description: Some times, the PC is DC-ed (disconnected) from the ISR as soon as my PC is up & running. sometimes the PC is DC-ed after 1 or 2 minutes. And VERY rarely it takes 30 minutes till the DC.. I'm really tired of this, any 1 knows what might possibly be reason for that DC problem? Thanks in advance. ----------------------------------- DC - Disconnect NIC - Network Interface Card ISR - Integrated Services Router ISP - Internet Service Provider Edit: Oh, By the way, The Connection is ICMP Flooded as well.
assuming you've tested stuff like cables and reseated NIC tbh you are best starting to test your firewall & possibly move system to DMZ if you have one test your firewall with some free / shareware here if your firewall checks out ok, perhaps a new NIC may be the answer BTW: what OS on misbehaving system ?
Well.. the OS was XP Pro SP3 but while tring to fix the prob, my HDD died so i needed to buy a new one (Drive C was the one to die). so I needed to install a new OS, so I'm trying the Win7RC at the moment.. I'll post ere again if the prob is not solved. if i'll figur it out i'll post as well.. 10x.
