Ejabberd 2.1.6 - sha_drv.dll missing

Hello,
I have set up an ejabberd (version 2.1.6)cluster on Windows network with two nodes namely mira1 and mira2.
Although I could configure the table copy settings of both nodes using the admin interface of mira1, after a restart, the second node does not start.
This node is complaining about the absence of a DLL = "sha_drv.dll".
I'm attaching the console output when the second node was run using "live" below this message.

It would be great if you could tell me what this means and how to solve this problem.
Thanks in advance
Sree
