We have one Mac (a MacBook Pro Unibody) amongst our Windows machines which connects to the "server" (actually a Dell running Windows XP Pro) to access documents. This works just fine most of the time, but sometimes after waking from sleep, it cannot connect to any Windows computer on the network.
There are no errors (nor even any messages) in the Console application when attempting to connect either by the Finder's network browsing, nor when using the "Connect To Server" menu, either by name or IP.
I have tried "Relaunch" on Finder, toggled File Sharing, disabled and re-enabled the Airport, but nothing makes the Mac able to connect again until I reboot it!
Other computers can connect to the machines, so it is definitely the Mac at fault.
Are there any workarounds that anyone has found? Is there perhaps a way to re-start the samba client?
The laptop is indeed using wireless, but all network connectivity is working, the Mac can ping the XP host it's trying to connect to and browse the internet just fine. I've tried using the IP address of the host machine in the "Connect to Server" menu item; That is now mentioned above.
