Re: Intermittent outages on two subnets on 2003 server

Hi there,

Just wondering if anyone could help me with a problem we are
experiencing. We have a server running with two NICs on two seperate
subnets going out on two different VLANs. The firewall cannot route
between the two firewalls and we are working to try and get the
routing sorted.

I have a subnet on each NIC and intermittently we are having outages
on each subnet. I have a continuos ping running against each subnet
and there seems to be brief 5-10second outages on alternate ranges.
There doesnt seem to be any pattern between the issues.

We have websites running on each of the subnets and obviously the
sites go down when there is an issue.

Anyone any ideas?


I assume this is related to your other thread. I'm not sure if it is because of the way you've configured the server (multiple NICs with multiple gateways), or because of your routers/firewalls. If I may suggest, you said you may have to wait for the new firewall to come in, in order to be able to route between the subnets that you currently can't. That may be the solution.

FYI - For anyone else that would like to help and attempt to diagnose this for Fox1977, please refer to the original thread for more information concerning the current setup and other info:
