I have a Vista wired computer with printers attached and an XP wireless computer in the same "workgroup". The Vista compter can see the XP computer however the Xp cannot see the vista computer or printers. File Sharing and Network Recognition have been activated. Both computers employ the WindowsFirewall and Microsoft Security Essentials, there is no other spyware installed. I have changed the name of the workgroup several times which has not resolved the issue. Suggestions for resolution would be appreciated, TKS,BB3BB31 person got this answerI do too

Below you will find general network troubleshooting steps. If going through them systematically doesn't help, MVP Hans-Georg Michna has a Small Network Troubleshooter which often will pinpoint the cause of the problem. http://winhlp.com/wxnet.htm Excellent, thorough, yet easy to understand article about File/Printer Sharing in Vista. Includes details about sharing printers as well as files and folders: http://technet.microsoft.com/en-us/library/bb727037.aspx 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/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. In Vista, turn Password Protected Sharing ON. 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: XP - Configure Windows to Automatically Login (MVP Ramesh) - http://windowsxp.mvps.org/Autologon.htm Vista - Start Orb>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 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. See the first link above for details about Vista sharing. MS-MVP - Elephant Boy Computers - Don't Panic!
