Could someone advise me what to do with a such problem: I have a domain on samba-3.0.9-1 on linux redhat 7.3. And it worked properly, but recently several users (pc with Win XP) became not able to log in to domain (error message looks like : Controller of domain is down or Account of your computer isn't found), but at the same time the rest of users is able to log in. next day other users became not able to connect ... (though here are several ones which connect without problems). in a logfile i see the such suspicious strings: Got user=[] domain=[] workstation=[wrkst001] len1=1 len2=0 secrets_fetch failed! no entry for trusted domain MYDOMAIN found I have checked everything as I know. But couldn't solve the problem . Sasha
