Thank you, Nick. Where would we be without you? I only blame myself, but I am not really aware what went wrong. Next to the webconfig I use webmin for things webconfig doesn't handle well like LVM, RAID or iSCSI configs and of course the file manager. Sometimes, while working in webmin, I would get a notification of new sofware which I normally blindly accept. That's probably the cause and, yes, I have probably also used webmin for making Samba changes. While I will not blame anybody besides myself I find it peculiar that this problem can still arise so easily and it is so difficult to deal with. Rebuilding my very simple server wouldn't be difficult. I am just a bit embarrassed this would still be necessary as this seems to have been a common problem for years. But your help is greatly appreciated!
