can't browse computes on the network

There is a network with about > 10 PCs (WIndows 7 Pro) without a file server.
When I open "My Computer" and choose "Network" on left window pane, I can't see ANY COMPUTER listed.
I thought when you install WIndows 7, by default, network device discovery function is enabled. Apparently it is not on any of the computers on this particular network.
Also when I ping a particular PC on the network by computer name, it does not give me 192.168.1.x. Instead of it displays long numbers and digits with a lot of ":".
How can I display computers on the network and how can I display IP v4 address when I ping the computer name?

Network discovery is actually disabled by default for Public Networks in Windows 7. If the Network type is set to Work or Home then it should be enabled. You will need to check the type of Network the PCs are on. You can enable Network Discovery using the steps in this article: http://windows.microsoft.com/en-au/windows/enable-disable-network-discovery#1TC=windows-7

Also when I ping a particular PC on the network by computer name, it does not give me 192.168.1.x. Instead of it displays long numbers and digits with a lot of ":".

Sounds like the PCs are getting an IPv6 address from a DHCP server. You'll need to log into whatever device that is handing out the IP addresses (generally a router or server) and disable the DHCP scope for IPv6. Without actually knowing what device is handing out IPs though, I can't really give you any further info to disable it.

To find the IP address of your DHCP server, type ipconfig /all | findstr /C:"DHCP Server" in Command Prompt on one of the PCs and it will return with the IP address of your DHCP server.

No, they are not. Network cards get their own IPv6 address from OS.
IPv6 don't need DHCP for local network, those are link-local addresses and start with fe80::/10 and last half of the address is randomized in case of Microsoft.

And why do you think you should have 192.168.1.x addresses? Is there a DHCP server? Or do you assign IPs manually?

I have not set up this particular network. When I was onsite first time, I saw 12 workstations with no file server. When I type IPCONFIG, I see gateway address to be 192.168.1.1 which is also DHCP server, but I can not get into it.
I suspect this is Time Warner Internet service provider's cable modem. I can run IPCONFIG and determine IP address of each PC, but pinging by computer name does not return typical v4 IP address in 4 Replies.
Let me try the suggestions above and post the result.

You use IPv4 and IPv6 addresses.

To ping with ipv4 address you can
ping -4 <hostname>

For discovery of IP addresses on unknown network I usually use Advanced IP scanner v1.5 there is a newer version but it is much slower.

I discovered that "Network discovery" was not turned on. So I turned it on and clicked [Save changes] button as shown in the screenshot. However it does not keep the change.
I tried to turn it on for both HOME and PUBLIC, but the computer simply refuses to keep the change. It goes back to "OFF".

when I added -4 in PING command, it returned a v4 IP address.

You could go to the network settings on each workstation, and turn off IPv6.

Make sure the following services are Started:
DNS Client
Function Discovery Resource Publication
SSDP Discovery
UPnP Device Host
Try enabling Network Discovery again.
