[Samba] Too slow to open shares.

[Juerlee (PLS CN)]

Hi,

I have experienced a performance problem recently on Samba 3.0.21pre1.

My server is configured running under 'user' mode, and I also created a
share with guest access enabled. If there is an invalid entry in DNS
setting, when I type \\server_ip_address, it is very slow to list the share,
then I click on the share, it takes at least 2 minutes to open the share.
After I simply removed that invalid DNS entry (say even I can not ping that
name server) and then restarted the Samba service, everything worked fine.

I checked the Samba configuration, after I set 'client use spnego' and 'use
spnego' to 'No', then I restarted the Samba service again, everything worked
fine even the invalid DNS entry exists.

Can anybody help?

Thanks in advance,
Juer
