PowerShell: Copy-Item fails despite the same process working with Windows Explorer

Question

I have a script that needs to copy files on a regular basis (every hour). I can open the source and destination folder using windows explorer and copy the file without issue.

However, if I try the same thing in PowerShell I get an Access to the path is denied error. I've checked the permissions on the share and I have full access. Why does this fail through PowerShell?

Copy-Item command:

Copy-Item \\idmststtrm2\tns_admin$\tnsnames.ora -Destination \\bts13r2b\tnsnames -Force

Errors:

Copy-Item : Access to the path '\\bts13r2b\tnsnames\tnsnames.ora' is denied.

Edits:

When I execute a Get-ChildItem against the destination path, I'm able to see the folder contents.

Results from get-item:

get-item \\idmststtrm2\tns_admin$\tnsnames.ora

Directory: \\idmststtrm2\tns_admin$

Tried using xcopy:

xcopy \\idmststtrm2\tns_admin$\tnsnames.ora \\bts13r2b\tnsnames\tnsnames.ora

Access is denied.

Answer 1

This problem is due to permissions writing to a network share. While the share permissions were set correctly, the NTFS permissions were missing. A system administrator will need to ensure both sets of permissions allow for the account to write to the folder. Once this was updated correctly the script was able to perform a copy to the network share.
