Suggests either incorrect Network driver
Also found this on another tech forum:
This problem happens when the server computer does not have enough disk space to store the image file. To resolve the problem, store the image file on a different computer, or free up sufficient disk space on the server computer.
Other causes and solutions
This problem sometimes happens when mapping a drive to a different server. To resolve the problem, use a UNC path for the server, or install Ghost to the second server and run Ghost from there.
This problem has been seen when using the wrong DOS drivers for the network interface card (NIC), such as drivers that are for a different model of NIC. Obtain the correct DOS drivers from the NIC manufacturer, update Ghost to use the new drivers, and then create a new boot floppy disk that uses the new drivers.
If the client computer uses the D-Link DFE500TX NIC, using the NIC's packet drivers instead of the NDIS drivers sometimes resolves this problem.
This problem has been seen when the client computer has more than one NIC.
This problem has been seen when the server computer has more than one NIC. Ghost does not support running Ghost Multicast Server, GhostCast Server, or Ghost Console on a computer that has multiple NICs. To resolve the problem, remove all NICs but one before running Ghost Multicast Server.
This problem has been seen when the server computer has more than one IP address. To resolve the problem, remove all IP addresses but one before running Ghost Multicast Server.
