Cannot access Remote Desktop within the network

The computer is an XP system that can access remote desktops on other computers, but other computers do not have access to the remote desktop of the XP system computer.

Since you can access other computers, the network connection is normal and may be caused by computer settings.

First, right-click My Computer, open System Properties, switch to remote, and select Allow users to connect remotely to this computer.

Then check the firewall settings, select "Settings" → "Control Panel", select "Security Center", then switch to the General option and select Enable.

Finally, switch to the Exceptions tab. In the Programs and Services list, select Remote Desktop.
