Hi All!
This problem occurs if the Link-Layer Topology Discovery (LLTD) Responder component is not installed on the Windows XP-based computer.
In order to establish the connection between the windows 7 machine and XP machine, try downloading and installing the Link-Layer Topology Discovery (LLTD) hotfix. Check the link mentioned below:
Link Layer Topology Discovery (LLTD) Responder (KB922120)
If this doesn't help, can the computer ping each other?
To do this:
- Get your computer name (Visit http://windows.microsoft.com/en-US/windows-vista/Find-your-computer-name for help getting your computer name). In this example we'll be using Computer1 and Computer2as the computer names.
- On Computer1, Click Start, type cmd and press Enter
- In the black and white command box, type ping Computer2 and press Enter
You should get something similar to the following:
Pinging <###.###.###.###> with 32 bytes of data:
Reply from <###.###.###.###>: bytes=32 time=77ms TTL=28
Reply from <###.###.###.###>: bytes=32 time=80ms TTL=28
Reply from <###.###.###.###>: bytes=32 time=78ms TTL=28
Reply from <###.###.###.###>: bytes=32 time=79ms TTL=28
If you get Request Timed Out, there's a something blocking communication between the computers.
Try those steps out and let me know what works!
