I have a strange issue here. I have a windows server 2003 R2 which need to manually add some routes. I used route add -p command but found that the routes still be removed automaticly even the servers in keep alive without reboot. I suppose that windows 2003 would automaticlly remove static route not be used for 48 hours?
