Just because this is so rare .. are you 100% sure there isn't a keyboard problem? Maybe a key is sticking and not sending out the right character?  (Just try all chars in the password as the username so you can test)

There is gooda build in administrator account and vulnerability andif password is changed without your knowledge, likely someone has reset by login into admin account, should be domain admin account and if audit policy is enabled, there is possibly traces indicating last login and changes logged.

Also try login from another machine, with old password and 'new' one. At this juncture, I leave those gpo sync aside...do restart machine too.

Are we talking about
a) the "true" Administrator account which is disabled by default during the install of SBS?
b) the admin account created during the install?
c) another domain level admin account created (such as your personal logon)

Who else has access to your server (physical or remote) at the Administrator level?

You can try the utility here...it's been known to work on SBS

You could also try logging on in DSRM which most likely has the old password

No it is not True Administrator account, i know it is disabled by default..
this is personal administrator account, i do have another administrator account but when i try to logon via another administrator account it gives message "The User Profile Service failed to logon. User Profile cannot be loaded"

Thanks.

Have you tried DSRM (offered during boot up by hitting F8)
Forgot to include the link for the password reset utility in my first response

Had a similar issue, thought I was going mad, or had been hacked.  Admin password didn't work, users complaining they could log on.
Rebooted the server (manually), and now everyone can log in!

Scary!
