RE: SAM file editing

Its not quite the same as "editing the SAM"
But,
Say you find the Domain Admin password is "abcdefgh"
And you login locally on your machine and set the local admin password to
"abcdefgh" as well.
Then when you try to access the network while logged in as the local account
you may find that you can get domain level access because the MS
authentication doesn't seem to check the domain and just passes through the
username and password.

I know this works for ipc$ shares but has anyone got any documentation on
any other exploitations of this.

Is it possible to edit the SAM file in NT4.0 without using an external
program?  I have an incident where someone gave himself administrative
rights the domain but insists "all" he did was modify the SAM file on the
local machine.  This doesn't sound right but I am not sure.  Thanks for any
help...
