When your direct cable connection through a parallel port has been inactive for 20 to 40 seconds, the connection may be disconnected. Note that this problem only occurs when you use a parallel port for direct connection from your Windows 98/95-based computer to a Windows 2000-based computer.
The problem is caused by a failure in the Windows 2000 parallel port driver.
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:

The English version of this fix should have the following file attributes or later:

To work around this problem, use either of the following methods:

Method 1

Use a serial port instead of a parallel port for the direct cable connection.

Method 2

Use a batch file to continuously ping the Windows 2000 host from the connecting guest. A continuous ping can be performed by using the -t switch and specifying the IP address of the Windows 2000 Host. The IP address of the Windows 2000 host could be the assigned address of a connected network adapter, or the first address in the configured pool of addresses for connecting clients.

For example:

pool = to

Use the command:
ping -t
Microsoft has confirmed that this is a problem in Microsoft Windows 2000. This problem was first corrected in Windows 2000 Service Pack 2.
