When you try to connect to a remote Microsoft Windows XP Service Pack 2 (SP2)-based computer by using the AutoCAD File Transfer Protocol (FTP) service, you may not be able to open a project.
This behavior occurs because the remote computer that you are trying to connect to has Windows Firewall configured to block the AutoCAD FTP service. The AutoCAD FTP service uses TCP port 21. By default, Windows Firewall has TCP port 21 turned off.
To work around this behavior, turn on the AutoCAD FTP service on the remote computer that AutoCAD is trying to connect to. To do this, follow these steps.
  1. Click Start, click run, type ncpa.cpl, and then click OK.
  2. Right-click the appropriate connection object, such as a dial-up adapter or a network adapter. Click Properties.
  3. Click the Advanced tab.
  4. Click Settings.

    If Settings is not available, click to select the Protect my computer and network by limiting or preventing access to this computer from the Internet check box, and then click Settings.
  5. Click to select the FTP Server check box, and then verify that the name of the computer that is in the Name or IP address of the computer hosting this service on you network text box is the local computer.
  6. Click OK three times.

Similar behavior may occur in other programs that use FTP to connect to remote computers that are running Windows XP SP2.
