About Address Books

An address book is a collection of items called connections with each connection representing a remote PC. Address books are loaded and displayed in the Viewer.

Address book components

Connections have properties that define specific characteristics of a remote session, such as the destination IP address or Internet-ID code, access password, color depth and so on. Connections can be grouped into folders.

Address book types

Address books can be of the following types:

An example of a local address book is the "General address book", which is a special kind of address book created for you automatically once you install the Viewer.

Using search

Use the instant search function to quickly find a connection in a given folder or address book. Start typing in the search field 1 and the Viewer will be updating the search results 3 on the fly to match your search criteria:

Address book search

Search scope 2 is limited to the currently selected folder or address book. If you want to search in a different address book just select that book in the left pane.

Connection status

Connection statuses show whether the remote Host is online (available) or offline. The connection icon shows the relevant color and text for each of the statuses:

Connection icon colors and labels

"Logged on" status

The connection icon displays a green monitor and the text label says LOGGED ON. This means that the remote Host is accessible (online) AND you are currently being logged on to the remote PC.

When in the LOGGED ON state, you can immediately start a remote session in one of the available connection modes without entering your access password. This is because being logged on means that you have already authenticated on the remote Host.

"Online" status

The connection icon displays a yellow monitor and the label says ONLINE. This status means that the remote Host is accessible, but you are not logged on it yet. Use this status to determine which of your Hosts are available for immediate logon/connection.

The program performs online check immediately when you add a new connection and then at regular intervals afterwards (each 30-60s).


By default, the online status is checked automatically only for Internet-ID connections and not for direct connections. To turn on online status checks for direct connections, enable Check online status for direct connections on the Security tab in connection properties.

For other ways to check the online status and for description of the relevant Viewer options please refer to the Checking online status page.

"Offline/Unknown" status

The connection icon displays a black monitor and the label says either OFFLINE (for Internet-ID connections) or UNKNOWN (for direct connections). This status means that the remote Host is unavalable due to one of these reasons:

  • Host is not installed or not running on the remote PC;
  • Host is not configured properly, e.g. uses a different Internet-ID server than it should use;
  • Something prevents the Host service from working properly, e.g. antivirus software;
  • The remote PC has no network connectivity or is turned off;
  • The Viewer cannot reach the Host because of overly strict network security on the Viewer side or an incorrect Internet-ID code/IP address of the remote Host.

As you can see, there may be different reasons why the remote Host cannot be accessed. The remote PC being offline, i.e. having no network connectivity, is only one of them.

For a complete list of possible reasons and solutions to the "cannot connect" problem for each connection type please refer to Internet-ID connection not working and Direct connection not working troubleshooting articles.

Multiple records — one remote PC

Any given connection in your address book is simply a shortcut with saved properties/parameters. This shortcut lets you initiate a remote session with the remote PC which is represented by the shortcut.

Therefore, the same remote PC can be represented by multiple connections in your address book, each with different properties. Let's illustrate this with an example:


You remotely connect to a computer in your office on a regular basis. When in the office network, you can connect directly over your corporate LAN using the local IP address of the remote PC. When outside the office network, you can connect via the Internet using an Internet-ID as the destination address because local IP addresses do not work on the Internet.

Now you can create two connection records in your address book that cover these two scenarios. One record (let's call it "My PC - LAN") will have the IP address of the remote PC as the destination address. The other record (let's call it "My PC - Internet") will have the Internet-ID of the remote computer as the destination address.

The two records may have different connection properties. For example, since connection over a LAN is the fastest by definition you might want to increase the color depth in the "My PC - LAN" connection properties up to the maximum of 24 bits (TrueColor). Conversely, in the "My PC - Internet" connection properties you can decrease the color depth to 8 bits to accommodate to not-so-fast Internet access. Having two different records for the same remote PC will save you time adjusting the properties each time you connect from a different place (e.g. a local network vs. an Internet cafe).

Under the hood

Technically each book is a single XML file. When you first install the Viewer, the program automatically creates a blank address book for you called "General address book". By default, the general address book file is stored in this location: C:\Users\<user>\AppData\Roaming\Remote Utilities Files\connections_4.xml.

The general address book is a special address book. You cannot delete it or sync it using the automatic sync option. In other respects this address book works the same way as custom address books that you create.
