Maybe someone has been through this already and can provide a
solution... I don't see anything in my Google searches or in the
O'Reilly troubleshooting section.
Running 2.2.8a with LDAP on Redhat 9, up to date with all the RHN patches.
Samba coordinates browse lists with another Samba box on a remote
network (via a VPN).
All workstations on both subnets use my local Samba box for WINS, as
mandated by dhcpd on each subnet.
I have the network neighbourhood browsing thing aced across the subnets.
Doing WINS lookups on the Samba box locally with the nmblookup command
gives instant response.
Windows workstations have mapped drives to the Samba box. They open
If I try to browse the shares of any machine on the network via network
neighbourhood, I see a 10-15 second delay before I get a result. I get
the same delay if I try to ping any machine on the network by name,
using the MS-DOS window. If I issue a 'net view \\machinename' command,
I get the results instantly. It's just the network neighbourhood
browsing and pinging by machine name functions that exhibit this delay!
Winpopup seems OK. It looks to me like the workstations revert to a
broadcast method of finding the requested machine, but only for these
commands. But I really don't know what the issue is!
The network is mixed Win2K and Win98/ME boxes. All seem to have the
I had been running an older Mandrake box with a newish version of Samba
(several versions over the years) in place of this present server. I
did NOT see this problem then. I copied my settings from the old server
to the new one (smb.conf) and soon noted the problem. This is what
makes me think it's a configuration issue, but from what I can see,
everything is correct. Firewalling is not active.
wins.dat is being kept up to date. So is browse.dat.
Any ideas? At this point, I'd settle for suggestions of where to look,
but an actual solution would be gold!
