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.
In Windows 7, go to Control Panel>All Control Panel Items>Network and Sharing Center. Click on "Change advanced sharing settings". You don't want to use Homegroup unless you have all Windows 7 machines. If you do and you want to use Homegroup, see Windows 7's
Help & Support. Otherwise, in the Advanced Sharing:
Turn ON network discovery
Turn ON file and printer sharing
Turn ON sharing in the Public folder sharing section
Turn ON password protected sharing
A. Configure firewalls on all machines to allow the Local Area Network (LAN) traffic as trusted. With Windows Firewall, turning on Windows 7's File and Printer Sharing as above will take care of this for you. If you aren't running a third-party firewall or
have an antivirus/security program with its own firewall component, 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.
Refer to any third party security program's Help or user forums for how to properly configure its firewall. 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:
Start>Search box>type: netplwiz [enter]
Click on Continue (or supply an administrator's password) when prompted by UAC
Uncheck the option "Users must enter a user name and password to use this computer". Select a user account to automatically log on by clicking on the desired account to highlight it and then hit OK. Enter the correct password for that user account (if there
is one) when prompted. Leave it blank if there is no password (null).
D. If one or more of the computers on your network is XP Pro or Media Center, turn off Simple File Sharing (Folder Options>View tab).
E. Create shares as desired. In Windows 7 I usually share out the user's Desktop and the Public directory.
