Istation is a fully animated, multimedia application and, as such, is not generally supported in a thin-client environment. Ncomputing supports Istation using specialized installation instructions. Please contact Istation Support if you have questions about compatibility.

Installation Information

To install Istation, you must be logged in with administrator rights. A simple installation is performed from our Download Istation Web page. There are no CD-ROMs to install or school-based servers to maintain. Administration for schools is virtually nonexistent. After installation, we can support any number of students simultaneously in Istation generally using the bandwidth of a single Web surfer. In the event that the school's Internet connection is lost, Istation will continue to function normally and will synchronize with our servers when the Internet connection is restored. Since Istation is delivered through the Internet, we transparently provide enhancements without a service call, at no additional cost.

E-mail Access

If your district uses an e-mail filtering software or program, please white list the domain to allow inbound access via e-mail. This is our main method of communication with campus teachers and administrators.

Local Firewall Information

When a software firewall is active on a computer, the firewall must be configured to allow Istation to accept connections from the local network. On Windows, this configuration occurs automatically during installation. For information specific to your OS, please review the detailed installation instructions for Windows or for Mac. Additional information may also be obtained by calling Support Services at 1-866-883-7323 or 972-643-3440 (and pressing 2).

Firewall Configuration Test

Test your firewall configuration now using the Firewall Configuration Test utility.
