9. Android-VNC-Viewer (Free)
If you prefer VNC for remote desktop connections and don't mind configuring the router and have static IPs or a dynamic DNS host name, you might consider using this simple open source VNC client. It supports VNC connections to most VNC servers on Windows, Linux, and Mac OS X via Wi-Fi and Cellular connections.
Unlike the Wyse PocketCloud client, this app doesn't display advertisements and gives you pinch zooming for free. On the other hand, it can't automatically secure your connections. You'd have to use a separate app, such as ConnectBot, to encrypt your connection to the computer/server you're trying to remotely access.
10. Spiceworks Mobile (Free)
If your organization uses the Spiceworks IT management solution, you can use this client app to view your network and PC inventory, manage trouble tickets, and access and manage users with support of Active Directory. You can also communicate with other IT pros in the Spiceworks community to get feedback, help, or research.
11. ActiveDir Manager (Free or $1.99)
This is a must-have app if you work with the Active Directory in your organization. It lets you view and manage users, groups, and computers right from your Android. You can reset user passwords, disable or edit user accounts, adjust group memberships, and perform other basic admin tasks. It supports Windows Server 2000 and later with StartTLS, SSL, or no encryption. It can directly connect to the Active Directory server via Wi-Fi or VPN.
The only difference between the free and paid version is that the paid version enables saving of the LDAP connection settings and options.
12. Wi-Fi Analyzer (Free)
If you work with the Wi-Fi network at your organization you may want to use this Wi-Fi stumbler and analyzer app when setting up access points, checking channel usage, troubleshooting Wi-Fi issues, or doing Wi-Fi security auditing.
You can view and export the details of access points: SSID, MAC address, encryption, channel, and signal in negative dBm levels via a graphical bar and text readout. You can view channel graphs showing each access point's channel and signal in real-time or a recent history. Then a channel rating page gives you recommendations on which channels to use. You can use the signal meter view to find the access points.
13. SharesFinder (Free)
This scans for Windows (SMB), FTP and HTTP shares/servers on the network you're connected to via Wi-Fi. It's useful if you're trying to access files on the network or when doing security auditing. For each share/server you'll see the IP and media access control address, SMB name, and vendor name.
This app also supports basic file transfers and management of the remote SMB files, such as creating and deleting files and folders. You can login as anonymous or input a username and password. For HTTP resources, it launches the Web browser. For FTP resources, you can connect via a third-party FTP client, such as AndFTP.
