I’ve run into the not uncommon situation where there is a SQL login and no one seems to have the password. We can change it and suffer the pain, create a new account, or try to crack it. I’ve opted to at least try cracking, using the article How to recover a SQL Server login password as a guide. Only took a few minutes to set up and I put just the hash for the one account in a file, and I bumped the thread count to 4. On my I7-3630QM with 8G it’s running at 65%, leaving enough for me to keep working. Once it starts the status screen below only updates if you press enter, you can see the time remaining is two days. Clearly this needs the GPU approach mentioned in the article. I’ll let it run for a while and see what happens, maybe 2 days is pessimistic!
