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:

  • A local address book (a "black dot" icon) is stored on the Viewer PC.
  • A synced (a "cloud" icon) address book is stored both on the Viewer PC and on the RU Server if automatic address book sync is enabled.
  • Active Directory tree. Learn more about Active Directory support.

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

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

Searching 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.

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, you can connect directly over your corporate LAN using the local IP address of the remote PC. When outside the office, 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).

Color codes and statuses

Connection icons use three colors and four text labels to show different statuses of remote PCs:

Connection icon colors and labels
  • Green. You are currently logged on to the remote PC. The text label says "LOGGED ON".
  • Yellow. This color can mean either of the following:
    • The remote PC is accessible over the network, the Host is running on it, and is awaiting connection. In this case the text label says "LOGGED OFF".
    • The remote PC is accessible over the network but there are issues connecting to the Host due to Host not running or not being installed. In either case the label says "HOST UNAVAILABLE".
  • Black. The text label says "IDLE OR OFFLINE". This color and label can mean either of the following:
    • The remote PC is accessible and the Host is ready to accept connections (i.e. it's idle), but no attempts have been made yet to connect to that Host. For example, the Host has just been added to the address book.
    • The remote PC is offline and/or not accessible via network.

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.
