Hi we currently have an Hyper-V production web server( WIn 2008 R2 std, IIS7). Our client accessess it to update, review contracts, contractor status and billing. Contractors use it to update the job status. Past few weeks intermittently the website is inaccessible and upon checking, its the NIC it just hangs. So we reboot and everything goes back to normal. During the time when the website is inaccessible normally you are unable to ping the LAN ip as well as the public IP. Last couple of days a new twist to the issue developed, now when the site is inaccessible, we are able to ping the LAN and public IP intermittently. Now when the site is down we are unable to ping internal or external ip and some days we can ping them just fine but the site is still inaccessible.. i have attached a web log reports. This issue happens once every 2nd day if not every day. Not sure what could be the issue. we are out of options.
so far we have
1. dedicated the NIC for production traffic.
2. Added 2nd NIC
3. seperated the traffic internal and external
since its a production issue we need this resolved soon.
