Hi Guys,
Got a bit of a mystery going on.
I have three machines hooked up in a simple network. Each one connected to a basic modem router via LAN.
Two of the machines are playing nicely with one another and have internet access also, one of the machines though is behaving oddly.
I should mention that this is a new setup, so no history to fall back on.
The problem is that the third machine will not connect to the network.
Symptoms/Test Results:
Visual Hardware check - the ethernet port shows activity when a cable is plugged in.
Cable check - Cables are working fine. Same issue shows up no matter what cable is used.
IP Configuration - When left to auto assign an IP address it fails - it ends up with a "limited or connectivity" error. If I assign an IP address to it the machine it appears to establish a connection. It shows data movement back and forth.
Router Diagnostics - The router is basic but the utilities of the router are capable of a simple Pass/Fail test on the ethernet connections. Whichever port is used the connection to the problem PC 'passes', although I do not know what that specifically confirms.
Ping - The problem PC has never been able to ping any of the other two machines. I once saw it achieve 50% success in pinging the router, although since then it has failed 100% of the time. The machine also usually fails to ping itself, although again, I once say a 50% success rate in pinging. (All of this when running from the manually assigned IP).
At this point I am beginning to think the network adapter is bad or maybe the driver, but I thought one of you might know of some sort of Windows XP setting or service that might affect this.
Anyone have any ideas?
Cheers.
