NIC stops responding during boot process

Hello

I had a server crash on my windows server 2003 this afternoon and since that
automatic reboot the server no longer communictates with the network.
When I ping the server it starts to respond during the windows 2003 start,
but stops to respond to the ping request, when the computer settings are
applied.
When I boot the server using "safe with networking", the server responds to
each ping and shows no problem. I already used to netsh to reinitialize IP
and WINSOCK, whith no effect. It's also not a problem within the network,
because the problem also exists with just one computer and the server
connected on one switch that has no connection to somewhere else...
I do not want to reinstall the whole thing: it's one of our citrix server
and it should be working on monday...
Has someone a real nice idea ?
Nicolas
