event id 2019 (DL 380 G3, W2K3)

[Ruegg Armin]

server soft crashes every 24 - 48 hours. believe i have upgraded all drivers & bios. since upgrading the nic drivers the team functionality does not work anymore. running symantec corp edition.
is it not possible to find the leak by some kind of monitoring tool?
for the time being i survive with daily reboot. the 2019 problems started a few days after i installed a new hp laserjet 4350 dtn. beyond that the server has not been touched for months.
kind regards, armin ruegg
