NO Network connection

[dd20]

Hello.

I have HP Proliant DL380 G7, with windows server 2008 R2 standard installed. the server cannot connect to the network. on the adapter setting, the cable plug is enabled but on the task bar the network icon keep showing cross red. the adapted drivers are well installedd and they are on board adapter.

i have tried using  PCI Express adapter but the problem persist. i tried windows troubleshooter the problem detected by the troubleshooter state " windows couldn't automatically bind ip stack protocol to the network. so i tried reseting the ip stack through command, but yet the problem persist.

Kindly assist to resolve this problem.
