Hello,

I have s5520hcr + 1 Xeon 5607 + 24GB + RAID1(2 SATA 750 GB)

Every 3-5 sec Windows 2003 hangs up for 0.5 - 1 sec. Process Explorer shows me 'Hardware Interruption and DPCs' takes about 50% of CPU every 3-5 sec. How to know what is going on and how to fix it?

Did you check if the drivers for your system have been updated to the latest ? Specifically the on-board NIC ? The Microsoft* Windows 2003 drivers for this product is available here.

Right, the problem was in wrong NIC driver that was installed by Windows as default. I reinstalled it from Intel and now it's fine. Thanks.
