All of the machines I'm testing are inside the firewall/router, although the N900 is running with a wireless connection. The N900 can access the shared media from the server, as well as connect to it via FTP, and HTTP so I haven't seen any indication that wireless should be an issue.

I unplugged the wired connection to my Windows laptop, disconnected all network shares, activated the wireless connection, then re-connected using the above net use command - the Windows laptop can connect to the share via wireless.

I am not using a Windows 7 homegroup, but rather a Netware 6.5 server offering SMB (aka CIFS) and NFS network shares. I cannot verify that NFS is working since AFAIK Windows does not include an NFS client, but have had no problems accessing the SMB share via wired or wireless connection.

Finally, if I substitute a garbage name for the Remote Directory in WM, I get the same Connection Refused message.

Is there a log, console, or any other way to see what the actual problem is?

Thanks
