a yellow mark is displayed over the icon network in Windows server.

How can i determine why and get rid of it ?

The server itself does have working internet connection for both ipv4 and ipv6.

Th yellow mark indicates that Windows has determined the status of the network connection is 'Limited'. This status indicator is determined by the Network Connection Status Indicator, part of the Network Location Awareness Service (NlaSvc). It's described in this Technet blogpost.

Briefly, it tests for internet connectivity by attempting to download a text file from http://www.msftncsi.com/ncsi.txt, so in order to satisfy this test and remove the warning icon you'll need the necessary DNS and HTTP access to do that. Once that's achievable, restarting the NLA service should be sufficient to change the indicated status.

Every time a network configuration event occurs (meaning that something has changed in the network configuration), the NCSI process performs several tests to identify the network’s connectivity status. The first step NCSI performs is a DNS query for www.msftncsi.com. The second step is and HTTP get request for http://www.msftncsi.com/ncsi.txt. This file is a plain-text file and contains only the text “Microsoft NCSI.” Last it will perform a DNS query for dns.msftncsi.com.

Is the machine able to resolve external DNS names? External DNS resolving needs to be in place for that icon to go.
