It is a bit funny on spanned images doesnt it give you the option to find it when it stops? How are you connecting to the drive? You can try differnet methods to see if it fixs it. Try maping the drive so you load it from drive ? try conecting via a share. Try connecting as a unc path.
If you have a server why not just use RIS its a lot better. Acronis is the best method for imaging now being a lot faster than ghost and more features. You can boot acronis start a restore and boot into the o/s while its loading the rest of the image and if you say select word it will pull that off the image first
