There is a Samba configuration option to treat names in case sensitive or case insensitive way:
http://www.samba.org/samba/docs/man/manpages-3/smb.conf.5.html

case sensitive = yes/no/auto

controls whether filenames are case sensitive. If they aren't, Samba must do a filename search and match on passed names. The default setting of auto allows clients that support case sensitive filenames (Linux CIFSVFS and smbclient 3.0.5 and above currently) to tell the Samba server on a per-packet basis that they wish to access the file system in a case-sensitive manner (to support UNIX case sensitive semantics). No Windows or DOS system supports case-sensitive filename so setting this option to auto is that same as setting it to no for them. Default auto.

However, there may still be problems because Windows is essentially case-insensitive. You may consider to create symbolic links named Folder1, Folder2 and Folder3 which point to the 3 folders, and then use these links to access the folders from Windows.
