Not on the Network

[ElaineC]

Hi all, i wonder if you'd be able to help me please:
I have a network with 6 pcs, 2 printers and a server. From the server side, all of the pcs can be seen but 3 of these pcs are currently unable to access folders on the server - even when logged in as administrator.
All 3 of the pcs can be accessed through VNC from the server but cannot be pinged. All pcs can ping the server.
The pcs also have outlook access which is accessed through the server and also accesses a shared database system via a Client Application.

When i try to access server folders from one of the machines in error, the following message appears: "\\Server\sharedfolder is not accessible. You might not have permission to use this network resource. Contact this administrator of this server to find out if you have access permissions. The network name cannot be found"

When i try to put the machine back on the network it says the network name cannot be found also.

All of these pcs were set up in the exact same way and have been running perfectly for the last year until this.

I would appreciate any input you may have.
Thanks

Please check your IP an NETMASK , I think 3 pcs there aren't in your domain or ip range, if you can't ping them seriously they have diffrent ip range or netmask.
