I've just tried adding some new users to a clients sme server (7.1.3) but they can't log on to the domain. Users who already have a cached profile on one of the pc's can log onto that pc, if the pc doesn't have their cached profile they can't log on.
I don't know when this might have happened as I haven't added new users on this server for around 6 months and in that time it has always had the latest updates applied each week.
It seems it may be an SID issue but I have tried changing the SID back to the one contained in the oldest backup of secrets.tdb that I have.
I have seen some other posts about this a while ago but there didn't seem to be a fix.
Does anyone know how to fix this issue??
