NAV Error: The program could not create a connection to the server.

Good day everyone,

I want to start this post by saying that I have VERY little experience with NAV but I have been thrown in a position where I have to be ‘the expert’ on the system.

NAV( Dynamics NAV 2013) just went down all of a sudden and I have restarted it multiple times but it is not coming up. The NAV on the server is functional but all the client machine say: “The program could not create a connection to the server. DO you want to try again?” Another thing is that my local internet connection will not work when I use the NAV DNS server but when I set it to obtain DNS server address automatically, the internet works.

I will really appreciate all the help I can get
