The network is 5 computer based. There's one printer connected to another
computer.
The computer with the printer can connect to every machine but 1, and that
other computer can connect to every computer, but the one that has the
printer. Anyone have a clue as to what's going on and how to fix it?
You haven't provided any information about your operating systems or your
network, so here are general network troubleshooting steps. Take the bits
that are applicable to your situation.
=====
For XP, start by running the Network Setup Wizard on all machines (see
caveat in Item A below).
Problems sharing files between computers on a network are generally caused
by 1) a misconfigured firewall or overlooked firewall (including a stateful
firewall in a VPN); or 2) inadvertently running two firewalls such as the
built-in Windows Firewall and a third-party firewall; and/or 3) not having
identical user accounts and passwords on all Workgroup machines; 4) trying
to create shares where the operating system does not permit it.
A. Configure firewalls on all machines to allow the Local Area Network (LAN)
traffic as trusted. With Windows Firewall, this means allowing File/Printer
Sharing on the Exceptions tab. Normally running the Network Setup Wizard on
XP will take care of this for those machines.The only "gotcha" is that this
will turn on the XPSP2 Windows Firewall. If you aren't running a
third-party firewall or have an antivirus with "Internet Worm
Protection" (like Norton 2006/07) which acts as a firewall, then you're
fine. With third-party firewalls, I usually configure the LAN allowance
with an IP range. Ex. would be 192.168.1.0-192.168.1.254. Obviously you
would substitute your correct subnet. Do not run more than one firewall. DO
NOT TURN OFF FIREWALLS; CONFIGURE THEM CORRECTLY.
B. For ease of organization, put all computers in the same Workgroup. This
is done from the System applet in Control Panel, Computer Name tab.
C. Create matching user accounts and passwords on all machines. You do not
need to be logged into the same account on all machines and the passwords
assigned to each user account can be different; the accounts/passwords just
need to exist and match on all machines. DO NOT NEGLECT TO CREATE
PASSWORDS, EVEN IF ONLY SIMPLE ONES. If you wish a machine to boot directly
to the Desktop (into one particular user's account) for convenience, you
can do this. The instructions at this link work for both XP and Vista:

D. If one or more of the computers is XP Pro or Media Center, turn off
Simple File Sharing (Folder Options>View tab).
E. Create shares as desired. XP Home does not permit sharing of users' home
directories or Program Files, but you can share folders inside those
directories. A better choice is to simply use the Shared Documents folder.
F. After you have file sharing working (and have tested this by exchanging a
file between all machines), if you want to share a printer connected
locally to one of your computers, share it out from that machine. Then go
to the printer mftr.'s website and download the latest drivers for the
correct operating system(s). Install them on the target machine(s). The
printer should be seen during the installation routine. If it is not,
install the drivers and then use the Add Printer Wizard. In some instances,
certain printers need to be installed as Local printers but that is outside
of this response.

Also please note that you may be bumping into the inbound connections
limitation if you have XP Home. The limitation is on *connections*, not
*computers*. Each computer can - and often does - make more than one
connection to a particular machine.
