Not sure this is a Samba problem, been a long time since I heard of 
Borland, so I went searching and found a few posts that seem to say that 
UAC is getting in the way, see here:

And here:

If you want my advice, roll Samba back and then go and find a 
replacement for your Borland database. Anything that relies on SMBv1 is 
on the road to nowhere, SMBv1 is going away fast.
