1. when you make your boot cd add mappings for the location of share for the images and a share for your applications, ie: imageshare = i:, program share = P:
2. In your distribute disk image job use the drive letter instead of .\ and check "Disable image path validation." ie: I:\MyImage.img
You shouldn't have this problem because you are not using PXE but make sure the automation pre-boot environment is set to default automation so you can use CDs instead of PXE.
If you are going to be deploying from multiple locations and you dont want to pull images\files over the WAN then have different cds for each location and use the same drive letters for the location of the images\files.
For example you have a site in New York and a site in California
The CA CD will map i to CA\Images and p to CA\Programs (assuming CA is the name of the server).
Then on the NY cd, map i to NY\Images and p to NY\Programs.
This will allow you to use the same job on computers in multiple locations.
