Set them back to the defaults again (10 or 15 in each case IIRC), set to zero they can cause serious speed issues and aren't needed unless you are experiencing the particular corruption issues that zeroing them fixes. AFAIK recent Windows 10 versions have fixed whatever MS broke in SMB that caused these corruption issues in VFP (and MS Access).
