Why do I have trouble accessing files on the Indiana Spatial Data Portal?

While trying to access the Indiana Spatial Data Portal (ISDP) or the Indiana Spatial Data Service (ISDS), you may experience one of the following problems:

• Inability to download files from the ISDP web site
• Inability to download files using the ISDP Multi-file Download tool
• Inability to view the ISDS from your web browser
• Inability to create a connection from ArcGIS software to the ISDS

If you are having trouble accessing these files or services, you may need to change your network firewall setting. Some firewalls are configured to automatically block all communication from nonstandard ports. Both the ISDP and ISDS use nonstandard ports for web communication. If you do not have administrative permission to make network updates on your computer, your organization's network administrator may need to make these updates. Note also that some security updates may need to be made at a higher network level than your personal computer. Again, consult your organization's IT staff or network administrator.

To access these services, set your network firewall to allow web communication from the following ports:

• 8290
• 8240
• 8306
• 8307

To manually open these ports using Internet Connection Firewall, follow the directions for your version of Windows:

Windows Vista

1. From the Control Panel, select Windows Firewall.
   
   
2. In the Windows Firewall window, select Change Settings.
   
   
3. In the Windows Firewall Settings window, click the Exceptions tab.
   
   
4. Click Add Port.
   
   
5. In the Add a Port window, type a name for the new port (e.g., ISDP Port 8290), and then type the port number (see list above).
   
   
6. Click OK, and then add more ports if necessary.
   
   
7. When you are finished adding ports, click OK.

Windows XP

1. From the Start menu, open the Control Panel. Click Network Connections.
   
   
2. Right-click your active connection (e.g., Local Area Connection) and select Properties.
   
   
3. Click the Advanced tab.
   
   
4. Next to "Windows Firewall", click Settings.

   Note: If the Settings button is unavailable, then the Internet Connection Firewall is not enabled on this connection, and you do not have to open any ports because they are all already open.

5. Click the Exceptions tab.
   
   
6. Make sure the TCP option is selected, and then click Add Port.
   
   
7. In the Add a Port window, type a name for the new port (e.g., ISDP Port 8290), and then type the port number (see list above).
   
   
8. Click OK on the Windows Firewall screen, and then click OK in the Local Area Connection Properties screen.
