[Samba] XP network breaks when shares are accessed by Fedora 19 smbclient

[How_F19]

I'll try again with a (hopefully) simpler example.

I am having a strange problem when accessing XP shared folders.

My XP box connects to internet via dialup, hosts my ethernet lan and 
provides Internet Connection Sharing to the lan.

The XP lan base is 192.168.0.0 and the XP user "Owner" is on 192.168.0.1 
and hostname is "WILLY".

My Fedora 19 laptop is dual boot win7/fedora19.
Booted to win7 I can see XP shares fine.
Booted to F19 I have problems.
That ends up on 192.168.0.148 with hostname "f19.splurge.org".
I do have an initial smb.conf but I am just trying to connect to
xp via smbclient at this point.

-----------
So here's what happens:

If I try to use smbclient to access XP shares on willy an alert box 
comes up on xp and dialup is broken.

If XP machine is NOT dialed up I do not get willy and instead get 
listing for f19.

Example:
-------------------------------

#### Attempt to connect to XP box "WILLY" via samba.
#### First with XP NOT connected to internet:

~>  smbclient -L WILLY
Enter howdy's password:
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 4.0.6]

         Sharename       Type      Comment
         ---------       ----      -------
        Share           Disk
         IPC$            IPC       IPC Service (Samba Server Version 4.0.6)
         Brother-HL-2240-series Printer   Brother HL-2240 series
         howdy            Disk      Home Directories
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 4.0.6]

         Server               Comment
         ---------            -------
         f19                  Samba Server Version 4.0.6

         Workgroup            Master
         ---------            -------
         WORKGROUP

#### I see NO mention of any shares I have on WILLY.
#### Everything there relates to "f19.splurg.org"'s samba server.
#### "Share" is the name of a share I designated in /etc/samba/smb.conf
#### howdy is my /home/howdy directory which is also designated to be 
shared.
#### Why don't I see any WILLY stuff???

#### Oddly, I think this is being sent to me from WILLY
#### When WILLY is rebooting I get this until it is fully loaded:

~>  smbclient -L WILLY
Enter howdy's password:
Connection to WILLY failed (Error NT_STATUS_UNSUCCESSFUL)



#### NOW I start dial up on the XP machine and try same:

~>  smbclient -L WILLY
Enter howdy's password:
Domain=[WILLY] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager]

         Sharename       Type      Comment

#### This is where the XP alert box comes up.
#### DNS is disabled for internet use but I can access files.
#### Above is listing showing my new  user "Buzz"'s shares as well as 
others.
#### I can browse and transfer ok:

~>  smbclient //WILLY/Buzzshare
Enter howdy's password:

blah blah

#### but at this point XP internet connection is severely insulted.
#### As said above an alert box pops up and dns lookup is disabled.
#### The alert box remains open waiting for my input: "file report" y/n
#### If I do not make a selection
#### I can still ping and browse using numeric addresses.
#### When I do make a selection I cannot get to internet on either
#### machine and I can not disconnect the dialup manually.
#### So I reboot.
