Try a program called DOMINO HASH BREAKER v1.0
It worked great for cracking hashes dumped from a lotus notes servers web
server. Not sure if the ID files are the same.

The hashes from the webserver look like this.

Any one familiar with a means of recovering/cracking the password for lotus
notes which resides in the .id file?

Any one know how the password is encrypted/hashed?

Thanks
Randy

        Hi,

If you're talking about the CachedLogonsCount registry key, there has been a
thread 2 weeks ago on FOCUS-MS :

http://www.securityfocus.com/archive/88/362946/2004-05-21/2004-05-27/0

Basically, storage is either in LSA Secrets or NL$ registry keys (depending
on Windows version), and there is no publicly available tool to decrypt the
hash. The stored value is a salted hash : NTLM( username + NTLM(password)).
This is hard to crack by brute-force if password > 6 chars.
