Vistas increased security can cause problems with network shares on Buffalo terastations.
These cheap raid 5 storage solutions are ideal for backing up images so if you would like to use them from a Vista workstation do the following:
select: start menu > programs > administrative tools > Security and configuration management
Select > Local policies > security options > Network Security: LAN Manager Authenticating Level
Set it to “Send LM & NLTM, use NTMLv2 session if negotiated”
You should now have no problems connecting and accessing shares on the terastation.
