My server has two adapters that connect to the same network.How can i ensure that the server has got network connectivity even if one adapter fails?
You can define the static Ip addresses to both the adapters so that you can have an idea which one is down at what moment. This is just to make sure that if one fails to connect, the other is there all the time.
Also make sure that the DHCP is off on both the devices and that they are using a static IP address. For example use static ip 192.168.1.201 at your server and set the static IP of both adapters to this one after turning off the DHCP.
This will make completely sure that if one adapter is down, you have the next one up and running and so your server is not down for even a second.
