Thanks for your help. It looks like some strange things are happening.
When I do the above where I get, then set the permssions on my local drive
it works fine. When I do it on a mapped drive I get the account not found
error after inserting the code above. However, if I try to add a domain
account permissions to the file then it doesn't give an error, but it
doesn't add the permissions either.
