Samba-NT Communication problems

[Leah McKelvie]

After I rebooted a unix server running Solaris 2.5.1, I was having
problems with people being unable to access shares through Windows 95 or
Windows NT that they had previously been able to access.  I was able to
fix the problem by setting public=yes for all the shares, but now people
are having problems accessing some of the directories under the shares.
Sometimes doing chmod 777 does the trick, but it doesn't always work,
and even if it did, I would not consider it a true fix, since we need
better security on those shares.   Does anyone have a fix for this?

Thanks.
