wireshark trace file

We have installed new samba 3.6.9 on our new rhel6 server, and it is very slow some time. Using wireshark, we found out every time the windows client send NTLMSSP_NEGOTIATE, the samba server responses NTLMSSP_CHALLENGE 10 sec later.
Hope anyone can help.

Comment 2 Volker Lendecke 2013-05-08 08:06:50 UTC 
looks like you got a hostname resolution problem... Is your DNS responding well, and do you have your own hostname in /etc/hosts?
Comment 3 Xiang Liu 2013-05-08 09:30:22 UTC 
I added the server name (which is defined in /etc/sysconfig/network) in /etc/hosts, and it works. This issue is considered solved. Thanks!
