After about 15 minutes, a Norton Ghost 14 backup fails with Error EBAB03F1: The specified network name is no longer available.

The source computer is a P4 laptop running Windows XP SP3. The target computer is a Core2 Quad desktop running Windows Vista Ultimate 64bit.

It does not help to disable Norton 360 on the source computer or Norton Antivirus 2008 on the target computer.

The Event Viewer consistently shows the same two VSS-related errors after Norton Ghost starts but before it fails. It makes no difference if the VSS service is started or stopped. The VSS errors do not appear elsewhere in the event log, only after Ghost starts.

The MSS event messages, however, are quite common, appearing throughout the log, and they may have nothing to do with the problem.

Here is the Norton Ghost error display...

-Errors exist.
--Unable to write to file.
---Error EBAB03F1: The specified network name is no longer available.
---Unable to set file size.

-----Error EBAB03F1: The specified network name is no longer available.

Here are the source computer events, with the final error 
at the top and the "Ghost Starting" message at the bottom:
