[jcifs] Strange error: BYFP0001

[darren.taft at bt.com]

I've worked around the ad-integrated DFS issue by connecting to our AD
using LDAP and querying for the DFS configuration.

I'm now trying to use one of the referred-to servers (i.e. connecting
directly to one of the servers, rather than using any DFS capability in
jCIFS).

When running the code from a Windows server, it works fine.  When
deploying to UNIX, I get an error returned:

ERROR: jcifs.smb.SmbException: BYFP0001
java.net.UnknownHostException: BYFP0001
	at jcifs.UniAddress.getByName(UniAddress.java:301)

	at jcifs.smb.SmbFile.listFiles(SmbFile.java:1613)
	at jcifs.smb.SmbFile.listFiles(SmbFile.java:1521)

Anyone got any idea where BYFP0001 is coming from?  It's certainly not a
path on our network.

The full output (with loglevel 3 set) is at the end of this email.

Cheers,

Darren
