Last friday my samba server stopped responding to new loggins
Nothing in the smb.conf was changed neither was anything else changed 
the redhat server (still need to upgrade but waiting on new office space to
deploy better hardware) was responding a little slow.
after investigating i noticed that the samba log directory was flooded with
false login attempts. an ls  command to minutes to process. I emptied the
directory en recycled the server.
I was still able to mantain connections allready opened but new logins are
still denied "because the computer account in the primary domain is missing
or the password is incorrect"
the network consists of xp,win2k and a few 98 machines
