Network Password issues

I am running Win 7 64bit Pro and was trying to connect to a ReadyNAS Duo v1 (sparc) with 4.1.12 FrontView and RAIDar 4.3.8 When I tried accessing my Duo I was constantly getting the dialogue box for Network User Name and Password when accessing through file explorer. I tried numerous Win 7 solutions posted in this forum and various other web forums all with no luck. Finally I allowed guest access in FrontView for CIFS portions. So once you are in FrontView (advanced mode), click on Shares --> Share Listing --> CIFS icon -->Default Access: switch from disabled to read/write --> scroll down and select "allow guest access" --> click apply in the lower right. Once I did this for each share I had, I had no problem accessing my ReadyNAS files and folders on the Duo.

I should say that in addition I have Win 7 Pro set to the following in Network and Sharing Center --> Advanced Sharing settings

Turn on network discovery
Turn on file and printer sharing
Turn on sharing so anyone with network access can read and write files in the Public folders.
Media streaming is on
Enable file sharing for devices that use 40 or 56 bit encryption
Turn off password protected sharing
Allow Windows to manage homegroup connections

I hope this is of use to others out there...believe me, I know how frustrating it is to keep keeping that network user name and password request!
