[Samba] File transfer corruption (NULL characters)

[Mike Cantrell]

I've got a couple of Solaris 7 boxes that are running samba 2.2.0. When I try to copy text files from a windows 2000 client to the server, the resulting file is filled with all NULL characters. I tried copying the same file to a NT server's share and there was no corruption.

When copying to the solaris share, the windows 2000 client eventually gives the following error:

The specified network name is no longer available

The servers actually work great when I'm on the local network or running over a PPP dial up. The problem only occurs when I'm on the network via a VPN connection (Permit/Timestep client running over a PPPOE DSL connection).I know that this is probably a problem with the VPN client or possible the network but I'm pretty stumped. I have no idea where to go next. Any help or insight would be greatly appreciated :)


Here's the relevant log with the debug level set to 3:
