Cant access the network drive used by the workgroup who uses the same wireless connection?

There are 5 computers in the office connected to the internet using the same wireless connection point, the main computer has a z drive which the other 4 computers have access to using the office wireless network and all computer work is to be saved to this drive for office access. There is a new desktop which i have connected to the internet using the same wireless connection but when i go to my network places - then entire network - then microsoft windows network, no domain appears so I cant access the network drives or printers.....I also tried another route.. tools - then map network drive and then I typed in the the same info on the other five computer but the computer still couldnt find the network drives they have. I have already typed in the encryption key to get access to the internet and then the network key to connect to the same network but for some reason i still cant access the network drives. Is there a special address or code I need from the main computer maybe?..

First things first, Can you ping the 'main computer'? By name and/or IP address





Does the new computer show up when you type net view in a command prompt?





You say in your question that the network drive is in a Workgroup, but in the detatils you mention domain. Big difference here. Some clarification would be a little more helpful.
Reply:Join domain/work group first ( name should be exactly same ).run network setup wizard from control panel and follow the instructions.check your sharing and users permissions.Now you should be able to see the drives.
