[Samba] Host Cannot Access Samba

Thanks for your assistance I have more information as requested:
Smb.conf was created from a template by the systems administrator of the file server
File server is running Red Hat 4.4.6-4
File server has Samba version 3.5.10-124
Client has box running Windows 7 and installed Virtual Box with Linux Centos 6.3. He has mounted a share to the file server samba share and can read the files. He has mounted the share with windows credentials. He can read files but not edit them on the Linux VB but can read/edit /delete from the Windows 7 box directly. He gets the error permission denied when trying to write through the Linux box.
He is using VBOX host with Bridged networking. Also the user noted that when transferring files from Windows to the samba drive that preservation of gid and pid was not achieved and may be the reason this share is not successful.
The logging below was a file generated specifically with his IP address in the title. Our logging for samba is set as follows:
# logs split per machine
log file = /var/log/samba/log.%m
# max 50KB per log file, then rotate
max log size = 50
So what the default level is for samba is what is being used currently. I have increased to logging level 10 and re-started a logging of files for the duration of trying to connect. Here are excerpts from logs:

And which Linux client are you trying to use? Very old versions of Samba can still work, somewhat, but be very difficult to integrate. Very new versions of Samba have a lot of features that your old CIFS server, whatever it is, may not know about and may not support.
Give basic information like what OS or Samba version your file server is, and what Linux version and what Samba version your Linux client are. And did your friend compile Samba from source, or use an OS provided verson? The "smb.conf" provided by most releases is a very good template to work with, and even better explored with the "testparm" tool to find out all the options that are being set by default.

Answers as follows:
- The linux VB is on a different network than the server
Does the VB host do NAT for his guest?
- I have a log file generated for that VB ipaddress with errors:
getpeername failed. Error was Transport endpoint is not connected
read_fd_with_timeout: client 0.0.0.0 read error = Connection timed out.
closed connection to service
This message isn't a problem: http://lists.samba.org/archive/samba/2011-March/161477.html
But is this everything that appears in the moment you try connecting? And on which loglevel? What appears in the log if you increase the loglevel and re-try to connect?
Please be a bit more generous with information. :-)
- Is this an AD or NT4 domain?
- Is the VB guest is joined to the domain?
- ....
