I don't know what antivirus you are using but to successfully copy a file from the server to a workstation do this. Copy the avg6226fu file to the script folder.
batch file should go like this:
::copy file
net use z: \\pdcserver\netlogon
copy z:\avg6226fu c:\%pathforAntivirus /y
net use z: /delete
::eof
For a domain, I recommend using Norton Antivirus Corporate Edition 8.0.
