Okay. Here the deal. have 2 networked computers using a trendnet wireless router. Mine is using a wireless connection while the other one is wired. Recently I got them on the same workgroup now they can share files... EXECPT The wired computer can ACCESS all the shared file and printers on the network while mine can't access any of the other computer files. When I go to My Network places then click on "View Networked Computers" and click on the other computer I get a message SAYING "oem-xmfl44eeluh (name of the computer) is not acessable. You may not have permerssion" or something like that. I've tried lots of stuff but it still happens. I know their networked right cause I can map a network drive to the Shared Documents folder. Only thing's I'm not liking is that the network doesn't auto update it self "If I add a new sharing folder, mine won't recognize a difference and i'll have to add a network place every time." and shared printers won't show up. Both systems are running Windows XP Home SP2. Please HelpWhat do you have installed as a firewall on the computer that connects wirelessly?

Check the settings on that firewall and make sure it is not blocking other network connections.Both are running Windows Firewall (I will update it...) and are configured to allow sharing filesMake sure (on the wireless one especially) that you are assigning your IP and DNS. This gets kind of complicated with wireless devices. When you connect to a network and just grab whatever IP your router has setting there, it's kind of "temporary". You can setup all of your file sharing and what not, but the moment you CLOSE that computer, you may lose all of your settings. This is a problem I was having for a long time. This may not be the case but is something you should look in to.

Right click on your wireless area connections and go to "properties" Then, highlight "Internet Protocol (TCP/IP)" and click on the "properties" button below. This is where you need to assign your settings. You may want to look further in to this option. You need to be familiar with your internal IP's and it is a good idea to set your router up to assign a CERTAIN IP to that computer.You have to check on the computer where you can't connect:
Control panel ->Administrative Tools->Local security policy->USER rights assignments->Access this computer from network->Everyone (check if the Everyone group is mentioned there).
Also, check that "Deny access to this computer from the network" has no mention about the user "Guest" (the "guest" account SHOULD NOT be there).

You will need a user account and a password on the "inaccessible computer".
