The 'net' command provides the setlocalsid and setdomainsid functions for setting the SIDs, there is no need to use hex editors.

I I remember there is some kernel bug on some versions of the kernel, that do not update the mtime when the file is mmapped, it may have changed just recently (and is probably so, as you would have had problems much eralier otherwise). > cannot say why the entrustment from this special machine has been broken, > but now I am able to log on to the domain as any user on all machines again. > (which have joined the domain before the SID change). > The only thing is that we added one machine after the modification of the > Domain-SID, we have to see how this machine behaves.
