Samba Connection Issue
 

I'm sorry but I don't know the proper place for this post, but this seems like the best spot.

I've installed Samba 3.6.6 onto a RHEL 5.1 server. The Share works for putting stuff in, however when a server attempts to take things out, it hangs at the discovery bit for a while, and then I get a message saying that the spot is no longer available on the network. There are no new Samba log entries made. I've tried several different sites posts for fixing this, ranging from editing the NetBIOS part of the Windows NICS, to changing smb.conf parameters.

Any and all help would be appreciated. Below is my smb.conf file:

[global]
workgroup = MYWORKGROUP
security = user
passdb backend = tdbsam

[share]
comment = a share
path = /share/shared
writeable = yes
available = yes
create mask = 0777
directory mask = 0777

Update:
I can transfer small files, ~18M, they just take a very very long time to go. However a file that's around 400M just sits with a bar going back and forth forever doing "discovery"
