CIFS Solution for Win7 x64
After many months of trying to get the CIFS share on my BD670 to work with my Win7 x64 machine, I finally stumbled across the fix. Give these a shot if you can't get CIFS to work. I do everything through CIFS now and don't even touch DLNA now that CIFS is working.

Found this elsewhere and it worked for me on Windows 7 Home Premium 64 bit:
Note I had also done what bujjodu's post suggested about the public share options a couple of posts before this one, but I don't think that did anything. I see all shared folders under my Win7 machine now just like the XP ones.
edit the following settings in Registry
-Click Start button and type regedit in Search box and select regedit.exe to execute
-Go to HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Lsa and change the value as follows
-Right click on "LimitBlankPasswordUse", select Modify and change the value data to 1
was already 1
-Right click on "NoLmHash", select Modify and change the value data to 0
originally was 0
-Right click on "everyoneincludesanonymous", select Modify and change value data to 1
original was 0
-Go to HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\Lan manServer\\Parameters, right click on "restrictnullsessaccess" select Modify and change the value data to 0
original was 1
-Reboot the PC again
My note: the above settings did indeed allow CIFS to work on the BD670 without entering a CIFS login and password. My shared folders simply showed up under the computer icon in the server list. However, after about 48 hours, the folders on theBD670 server screen would disappear and only a computer reboot would bring them back.

I'm not sure if this has been mentioned yet, but as I lost a lot of hair trying to solve this problem in the past, I thought I'd mention this relatively common issue here:
Windows 7 requires changes to the registry to keep the computer with the content on it from dropping the network shares. If you are having this problem, you must set the lanmanserver/parameters/size key to 3 (for a fileserver). Don't skip this step or you will eventually have annoying dropouts of your entire media library.
When you configure one of the four options for the Server service, the information is saved to the following two registry keys:
HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\lan mans erver\\parameters\\size
Your choices for this registry key are 1,2 and 3.
1 = Minimize Memory Used
2 = Balance
3 = Maximize Throughput for File Sharing and Maximize Throughput for Network Applications
Originally was 1
HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Sess ion Manager\\Memory Management\\LargeSystemCache
Original key is 0
Your choices for this registry key are 0 and 1.
1 = Maximize Throughput for File Sharing
0 = Maximize Throughput for Network Applications
Some programs, such as SQL and Exchange, set this value during an installation. For these programs, the optimal setting is 0.
0 = Indicates that the computer does not go outside its cache pool and use program memory to perform I/O functions.
1 = Indicates that the computer looks outside of its cache pool and uses program memory to perform I/O functions. This occurs if the cache is full.
