SCANNING NOT WORKING ON WINDOWS VISTA AND 7 BY DESIGN
Windows Vista Basic, Windows Vista Starter, Windows Vista Home Premium, Windows 7 Basic, Windows 7 Starter, Windows 7 Home Premium lack the local security snappin that allow scan to smb.
Some registry changes will have to be made.
Login as Administrator. Click the Start icon and in the search box, type Regedit and open the program that appears. If you are presented with a User Access Control dialogue box, please click Yes to continue.
Navigate to the following registry area:
Create the following if needed by right-click on Lsa (on the left panel) and select New -> DWORD (32-bit) Value. Name them:
Ensure that the above spelling and capitalisation is used.
Once created, edit these settings. To do so, double click on them to bring up the edit box. Change the settings as follows:
LmCompatibilityLevel = 1
NoLmHash = 0
After changing these settings, close Regedit and restart the PC.
Once you have done this go to Control Panel -> User Accounts -> Change your password. You don’t actually have to change your password so New password can be the same as Current Password but you do have to click on the Change password box at the bottom right of the window to make this work.
If the problem persists then it might be an issue with smb compatibility try the fix below
