I have a small office network running on XP Pro sp3. There are two computers and and a printer/scanner/fax wired to a router. Both computers can access the internet and the printer. The first computer can access all files on the second computer. The second computer can't access any files on the first computer. Both computers are in the same workgroup. I have checked the file share permissions. The computers were both seeing each other a few days ago. As far as I know, no software or other changes were made. It is possible that there was a change made on the second computer that I'm not aware of, but there is no one who knows.I can't come up with any more ideas. I've checked everything that I can think of. Could there be some random Firewall (native windows firewall) setting that I'm not aware of? Could an anti-virus program be blocking the sharing? I would be able to understand the problem better if neither computer could share files, but in this case, it's just the one that can't.The different error messages:1. When attempting to access files on computer #1 via a shortcut placed on desktop #2: The drive or network connection that the shortcut "xxx.lnk" refers to is unavailable. Maike sure that the disk is properly inserted or the network resource is available, and then try again.2. When attempting to access files on computer #1 via My Network Places on computer #2: \\Computer #1\shared folder name is not accessible. You might not have pemission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The network path was not found.All help is appreciated, as my business can't get any work done right now. 1 person needs an answerI do too

HiSound like Firewall blocking the connection.Make sure that the Software Firewall on each computer allows free local traffic. If you use 3rd party Firewall On, Vista/XP Native Firewall should be Off, and the active Firewall has to adjusted to your Network IP numbers on what is some time called the Trusted Zone (consult your 3rd Party Firewall instructionsGeneral example, http://www.ezlan.net/faq#trustedPlease Note that some 3rd party Software Firewalls keep blocking aspects of Local Traffic even it they are turned Off (disabled). If possible configure the Firewall correctly,or totally uninstall it to allow clean flow of local network traffic. If the 3rd party software is uninstalled or disables, make sure that Windows native Firewall is On .Windows XP File Sharing - http://support.microsoft.com/default.aspx?scid=kb;en-us;304040Printer Sharing XP - http://www.microsoft.com/windowsxp/using/networking/expert/honeycutt_july2.mspxWindows Native Firewall setting for Sharing XP - http://support.microsoft.com/kb/875357When finished with the setting of the system it is advisable to Reboot all the hardware including the Router and all computers involved.*Note. Some of the processes described above are done Not for Windows sake but to compensate for different Routers and the way their firmware works and stores the info about the computers that are Networked. .
