    i suggest you divide your Adudit into 2 portions;


    LAN Segment you can futther divide into Serevrs, Firewalls, PCS.

    for servers you can use Microsoft recomended tools ( for example-Microsoft Base line security Analiyser), Shark  Network Monitor for windows envoirment etc. for any third part application you will find some auditing module in the application. many things you can check like user accounts, password polocies, backup polices, server hardware health, H/A solution

    Firewall is very important, before you audit any H/W or Software firewall i suggest you understand LAN and Phusical network connection connected with F/W. after understanding connection you can check ACL, VPN, VPN Groups and polices, etc

    Desktop/Laptop computers are very important.

    WAN: you can check VPN Connection, Encryption types, Keys .....

    you may find millions of network scaner availible on web, you can use any but i recomend use multiple scaners for one purpose, compare outputs and crocc check.

    i also suggest dont install/run any third network monitor tool on a server, unless you know the impact, also please dont scan and live application
