Our HP���s have had *odd* behavior with LAG on the dual onboard NICS(intel I think).
It seems to have something to do with the phase of the moon and the version of the HP driver. Try rolling back the driver upgrade? -sc From: Harry Singh [mailto:hbo...@gmail.com] Sent: Wednesday, August 12, 2009 2:35 PM To: MS-Exchange Admin Issues Subject: Re: Strange Exchange Freeze I have a broadcom team of 2 nics doing dynamic link addregation (LACP) I've updated the drivers about 3 weeks ago, when the last maintenance window passed. I didn't notice anything else on the network at that time, but i'm looking at the cacti graphs of the switches right now..

I had to physically shut it down and bring it back up. Prior to the freeze i noticed some users were getting the Outlook prompt in their sys trays "Outlook is retrieving information from your server", I KVM'd into the box and everything froze, hence the reboot. Now rebooted, everything is up but i notice an that at times a few users are getting the same prompt -- I've never received or experienced this on the mail server, and it's been up and running for over 3 years without this kind of issue. What can i do to start the troubleshooting process ? I checked my physical disks and they are all okay. Memory utilization is abnormal either. Is there a specific counter inside Perfmon i can monitor ?
