For a unknown reason, one of our IIS server stops responding to external request after a couple of minutes/hours.
The only way i can make the IIS works fine is to open a web browser and then browse to a web site.
After that, ping and request to the IIS server coming from the external works.
It looks like the server is in hibernation or something like this but it is not.
Even if I reboot the server or restart the IIS services, it won't work either, i really need to browse to a web site to wake up the server.
I tried to Disable and then Re-enable the external NIC, but same thing.
What i'll try is to ask our web programmer to rollback to the previous version in case he changed something that affect the server, but he doesnt think it is possible (might worth a try).
I need some advices about this.
