Details:
With the introduction of Service Pack 2 and 3, Microsoft has enabled the Windows XP firewall, and made it an integral part of the operating system. To allow the Symantec Backup Exec Remote Agent to send and receive data, it must be added to the list of Exceptions for the Windows XP Firewall.

To add the Remote Agent to the Exceptions list, perform the following:

1. Open the Control Panel by clicking on Start > My Computer > Control Panel.
2. Double Click on Network Connections.
3. Right click on the connection for the network card, and choose Properties. (By default this will be Local Area Connection 1) (Figure 1)

4. Click the Advanced tab. (Figure 2)
5. Click the Settings button under Windows Firewall.

6. Click the General tab.
7. Verify that Don't Allow Exceptions is not selected. (Figure 3)

8. Click the Exceptions tab.
9. Click the Add Program button. (Figure 4)

10. Click the Browse button. (Figure 5)
