Win7 workgroup network view issue

[Bah77]

Hi All
I have 5 PCs connected to a switch in a workgroup mode, all PCs can ping each other & can access each other by \\computer name\share drive, but, only 2of the PCs can see all the PCs under my network, the rest can see only 3 out of 5 PCs.

Is there any restriction on the number of the viewed PCs under my network?

What is going wrong, restricting me ti view only limited number of PCs?

3 PCs are win7 Ultimate
2 PCs are win7 Pro

One Ultimate PC can see all PCs under my network & one pro PC can see all the PCs. The rest can only see. 3 PCs.

So my issue is not in connectivity, the issue is the view of all pcs under my network.

Thanks in advance.
