This is a problem I've been struggling with for about a day or so now, and I can't seem to figure it out.
iBook G4 running OSX 10.4.11 cannot reliably connect to smb/cifs shares hosted by a new PC running Vista Ultimate x64. Connects, mounts and authenticates just fine, and I can browse directory structures ok, but whenever I try a large data transfer, it drops the connection randomly and completely loses the share. So, I'm not able to transfer files or stream video/audio reliably.
I can do the same with my laptop accessing shares on an XP computer with no problem whatsoever.
Both the Vista system logs and OSX's syslog and smb logs show nothing out of the ordinary at all, also tcpdump shows normal usage.
I can only surmise that this is some sort of protocol conflict between Vista's SMB and OSX's SMB. I've tried disabling QoS in the Vista network adapter properties, and it doesn't solve the problem. I've also updated the firmware on my Linksys WRT54g, which doesn't help. Google offers no solutions to my problem.
Oh, and I have changed the Vista security policy to try and use LM and NTLM before NTLMv2, as outlined in some Vista/OSX sharing issues. But, that's not the problem because authentication is fine.
Any suggestions would be much appreciated.
