During a manual image creation.

I boot from the bootcd, type img
make a creation enter all of the proxy information
and somewhere between 80-100% complete the image
process stops and I receive the error:
"Failed to write to Proxy. See Documentation)

I have tried sending the image to our imaging server and our test imaging
server, same error, doesn't seem to be file dependant because it stops at
different times.
There is more than 15 GB available on both servers, not sure what to try,
any suggestions?
