Hi,
Per the Altiris® Deployment Server Error Codes Document -you can download a copy from kb.altiris.com-
"Repeat the operation to see if the problem occurs in the same manner again. Simplify the network by removing routers, etc. that might corrupt data. If a file is being read, recreate the file."
CAUSE "Data has been corrupted (e.g. in an image or on the network)."
Hope this helps
