Gigabit Problems

[tntcoder]

Hi,

For the past year my samba shares were working fine over a 100Mbit network, and I have now moved over to a gigabit switch.

I set up my windows vista client to use 7KB Jumbo Frames, the maximum it would allow. I also used the following command on my linux samba server to set a matching MTU:

ifconfig eth0 mtu 7000

Now, I can ping between the machines fine with <1ms timings, but samba shares take at least 30 seconds to open up/resolve but once it does it seems to work fine, where as before it was instant.

All my network dns settings are correct, I cant think why vista is taking so long to open/resolve a share? Vista syncs in fine at 1Gbps.

And my linux NIC:

eth0      Link encap:Ethernet  HWaddr 00:0C:6E:65:99:50
          inet addr:192.168.1.20  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:6eff:fe65:9950/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:7000  Metric:1
          RX packets:45742 errors:0 dropped:0 overruns:0 frame:0
          TX packets:745 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:3341685 (3.1 Mb)  TX bytes:143128 (139.7 Kb)
          Interrupt:18 Memory:feafc000-0

EDIT: for some reason i can only ping the linux box, from vista. If i try to ping the vista pc from linux it doesn't go through for some reason, not sure if this could be related to the problem?

Any ideas on how i can fix it?

Thanks

Jack

Thanks, yep explorer does just stop responding for around 30 seconds before finally opening the share. Its not linked to a domain controller or Active directory at all. I cant see how it can be an authentication problem as ive been using the config successfully for a good year and its only a 1 user system. The problems have literally occured tonight as ive moved to uni and replaced my 100mbit switch with a gigabit one. So im pretty sure it must be an ethernet configuration problem :s My samba config is very generic and basic as well cant see it causing any issues
