Win2k Workstation disappear from Network Neighbourhood

[Leon]

My network is running Windows NT4 domain. 14 identical
workstations have been added to the network with only
Windows 2000 Pro installed, no applications.
all workstations have static IP addresses. All
workstations can access the domain and log onto the
server. They can also browse the network but seven of them
never shows in the browse window.
I verified the IP settings including Wins server address.
I cannot access these seven workstation from the network.
I can ping their respective ip addresses.
In server manager, they appear greyed and they cannot be
accessed.

Any suggestion ?
