I am facing a strange problem while connecting a new windows 7 machine (will be referred as machine A) to a dell switch. Here are few points to better understand my problem:
- When machine A is connected directly to a switch port(lets say port 10), it gets connected.(gets IP Address from DHCP).
- When the same machine is connected through IO port(internal cabling as in offices), it displays "Network Cable is Unplugged" displaying a cross sign over connection icon in system tray.
- When any another machine(Vista or 7) is connected through this IO port, it gets connected instantly.
- When any other machine is directly connected to port 10 it works.
- When machine A is connected to any other port(I tried 5 different ports) using IO ports, it does not work.
The switch works in MAC binded configuration(Static Address) and I am sure that I'm not making any mistakes in configuring the correct port on the switch for the system's MAC.
Also I tried re installing Ethernet drivers, disabling-enabling, restarting system nearly 14-15 times but none worked. Please suggest any possible solution. Also feel free to ask if any confusion is there in the above literature.
Update: The internal cabling of IO port has been totally renewed. Also because Dell machine was in warranty, we asked them to check and they replaced the motherboard after some diagnosis.
