Slow network performance

Hi All,
Apart from random dropout from the network. Our IBM X236 server suffers slow
network performance. I've changed the server from CISCO switch to a netgear
switch on a test platform. Also tried 1000m full-duplex setup with no auto
negotionation on both ends. Still after few days (3-4) server drops the
connection. And while its working I get 90KBps upload/download with ftp
transfers.
I have treid changing BGE network cards to EM (intel 100/1000) still the
same result. Any idea's to nail this problem?
