samba stops updating user shares

[Shwick2]

When I share a new folder on my XP box it isn't picked up by samba after a while.

If I immediately connect to the network and share a folder samba picks it up. After about 10 minutes if I share another folder samba won't pick it up.

I notice the same problem with smbtree- after a while it doesn't list user shares.


After looking at wireshark I could see that samba stopped sending a "Name Query" to my XP box. XP was still refreshing it's registration about once every 5 minutes though.

I'm using samba 3.0.28a and have no firewalls on the lan, any suggestions are welcome.

smb.conf

[global]
netbios name = SHWICK_GATEWAY
server string = SHWICK_GATEWAY
interfaces = lo, eth1
bind interfaces only = Yes
map to guest = Bad User
passdb backend = tdbsam

socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE
os level = 65

domain master = Yes
dns proxy = No
wins support = Yes
invalid users = root

[Media]

Can anyone help?


I tried some stuff from the samba checklist.

The pc could ping both the samba server shwick_gateway and itself shwickhomepc.
The server couldn't ping shwickhomepc: "ping: unknown host shwickhomepc". It also couldn't ping shwick_gateway.
On the server when i do "smbclient -L shwick_gateway" I get "Connection to shwick_gateway failed (Error NT_STATUS_BAD_NETWORK_NAME)".
On the server when i do "nmblookup shwickhomepc" it returns the right ip. Also "nmblookup shwick_gateway" is successful.

It seems the netbios lookups are successful from the server and the wins lookups are successful from the pc. The wins lookups aren't successful from the server.

I have a bind setup on my machine, but I don't tell samba to check it because I want it using the wins server. I set "dns proxy = no". I get the same results with "dns proxy = yes".
