EXSI NIC troubleshooting.

Currently I have a dedicated an exsi 5.5 host at hostway running 2 web servers, just recently these 2 servers started to crash with a blue screen and reboot, after some dump analysis and extensive troubleshooting I've found out that these servers only crashes when they are connected to the network, if I disconnect the image from the network they stay stable. I wanted to check with someone here if anyone here has had similar issues and if I need to be looking at the server NIC as a possible cause? Any suggestions will be appreciated.

They said that the arp table from the switch was causing the isse, but it was a strange answer. I'm not really sure.

Yes, check the following and resolve if needed. All hosts and guest OS must be on the HCL and certified.

0. All firmware up to date in the ESXi Host, especially NIC firmware.

1. Make ESXi 5.5 is on the latest build.

2. Latest version of VMware Tools installed.

3. VMXNET3 interface driver installed.

Yes.

Also, keep in mind, everything was working just fine for months....

But nothing ever remains the same.... those four steps where we would start diagnosis and analysis.

2003 is going to be difficult one to fix, as OS is end of life, no longer supported.

The strange thing is that, Hostway did an emergency maintenance on their firewall yesterday and these 2 servers started to crash right after that. I have opened a ticket with Hostway and they have not got back to me.

The above steps are standard best practices you should have in order anyway!

For Security and Critical issues.

Not certain what firewall changes could impact an OS, and crash them..... what is the crash ?

Blur Screen of Death, Stop Error Code ?
