can't access samba share after kernel update

[dave76]

We have had Samba running just fine for several years. Recently, after a kernel update, we can see the shares but cannot access them. Typically we get a message to the effect 'network name is no longer available'. The temporary fix is to boot off an older kernel. The last kernel that works for us is 3.10.0-957.21.2. Anything more recent and Samba behaves as above. So I guess the question is what changed in the kernel after the version mentioned which affects Samba. Anyone have an ideas?

You can install the current CentOS Plus kernel (--enablerepo=centosplus) which has this fix rolled into it already or you can wait for Redhat to get around to fixing it eventually!
