Hope someone out there can help with a problem that won't go away!
We have recently replaced a load of 100mb hubs and switches with new Netgear gigabit kit consisting of GS748TS, GS724T & GS724TS switches linked together by cascade cables at the back and fibre links (AGM731F modules) to remote locations.
Ever since doing this we have had problems with a single server getting intermittent ping request time outs.
The server is an old Intel 2U Rackmount server with a SE7520JR2 server board running Windows Server 2003 Standard. This server board has 2 onboard gigabit ports. The 2nd card was not in use so we switched them over, patched directly into the switch with a new cable and updated the drivers but it still fails under load.
Fitted a new Intel Pro1000 MT PCI-X card into the server and this still fails.
Patched into another switch and this fails too.

had a similar issue so I too enabled "Fast Link" on the relevant port but it still fails. http://documentation.netgear.com/gs700ts/enu/202-10228-02/GS700TS_UM-06-12.html
The switch that this server is currently plugged into has the latest V5 firmware installed on it but I must admit that there are 2 switches on the network with version 3 firmware.
Am at a loss with this and the only things I have not yet tried are:-
1) Enable Teaming on the LAN cards
2) Drop the link speed back down to 100mb
Any idea's experts?
Thanks for reading.
