This Is Weird

So, trying to set up a File and Printer sharing network.

Computer 1:
Host Name: FAMILY-COMPUTER
IP Address: 192.168.1.103
Subnet Mask: 255.255.255.0 (class a)
Workgroup: WORKGROUP
Operating System: XP Professional
Connected Via: LAN

Computer 2:
Host Name: EMILYSCOMPUTER
IP Address: 192.168.1.101
Subnet Mask: 255.255.255.0 (class a)
Workgroup: WORKGROUP
Operating System: XP Professional
Connected Via: Wireless-G

Computer 3:
Host Name: ZACK-PC
IP Address: 192.168.1.102
Subnet Mask: 255.255.255.0 (class a)
Workgroup: WORKGROUP
Operating System: Seven Professional
Connected Via: Wireless-G

Computer 1 can access files and printers on 3 but not 2.
Computer 2 can access files and printers on 1 but not 3.
Computer 3 can access files and printers on none of them.

It's making my brain hurt. Any advice?

 

Computer 3, make sure it's logging in via a password and check what the WORKGROUP is listed as from it, a private or public network.

 

Yes, there is one account, Zack, administrator and password protected

 

What the WORKGROUP is listed as, private or public network?

 

What do you mean?

 

I'll throw in my 2 cents....

Try renaming the WORKGROUP to something different like ZDAWGNET on each of the computers using the network setup wizard. Sometimes Windows needs a good slap in the face like that to make the network 'work'. :-D Windows 7 uses 'Homegroup' which I'm not familiar with just yet. Hopefully someone else can help with any settings there if needed. Sometimes win7 will just 'see' it automatically, though.
