Hi Tony and Typoprone,
Many thanks for your suggestions. Typo, when you say remove the all the streams, are you referring to alternate data streams within the NTFS file system or something else? (I am trying to insert a Ghostbusters reference in here somewhere but have failed miserably).
Tony, thankyou for that article ID, it fits the bill exactly (and I should have done some better searching to find it myself), I have followed the article and deleted the archive points and recreated them, but still have the same problem. Where the article says:
"run the fsautility -a -s "UNCpathname" to re-create the Archive Point with the original ArchiveID" I ran it just as it suggests, but should I be passing it the original ArchiveID and if so, where would I locate this?
I created the dataset by copying and pasting files from a production file server. We don't run EV in production yet, but could this copying process have created data streams that EV is using somehow?
