If anyone is trying to access a windows SMB share and they are getting empty folders or invalid argument error in ZDMC do the folowing: open regedit from windows run navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters Create new DWORD or DWORD 32 with name SizReqBuf with decimal value 65535 restart computer and try access the share, worked for me. Funny thing is I only needed to do this for ZDMC all other file explorers app worked without it!!!
