[AccessD] Compacting DB with batch file makes MDB read Only

I have a customer who is doing nightly compacts. He runs the following in a
batch (.bat) file.

"C:\Program Files\Microsoft Office\Office11\MsAccess.exe"
"\\corp01\shared\GeneralDocuments\Corporate\EDI_DB\EDI.mdb" /Compact
Exit
 
Once it finishes compacting, the new DB is now read only in it's file's
permissions. Any ideas why?
