How to: Configure a Windows Firewall for Integration Services Access
The Windows Firewall system prevents unauthorized access to computer resources. To access Integration Services through this firewall, you have to configure the firewall to enable access. There are many firewall systems available. If you are running a firewall other than Windows Firewall, see your firewall documentation for information that is specific to the system you are using. The following procedure is specific to Windows Firewall.
To configure the Windows XP Firewall or Windows Server 2003 Firewall
In the Control Panel, double-click Windows Firewall.
In the Windows Firewall dialog box, click the Exceptions tab and then click Add Program.
In the Add a Program dialog box, click Browse, navigate to the Program Files\Microsoft SQL Server\90\DTS\Binn folder, click MsDtsSrvr.exe, and then click Open. Click OK to close the Add a Program dialog box.
On the Exceptions tab, click Add Port.
In the Add a Port dialog box, type RPC(TCP/135) or another descriptive name in the Name box, type 135 in the Port Number box, and then select TCP.
Integration Services service always uses port 135. You cannot specify a different port.

In the Change Scope dialog box, select My network (subnet only) or type a custom list, and then click OK.
