I am writing an app to display the active POS stations that can be seen from a PC. It is likely that station names will be duplicated but they will always occur in seperate "subnets". For example Windows explorer would show

Windows Network

Subnet1

Station 1

Station 2

Subnet2

Station 1

Station 2

I can easily ping Station 1 if there is only one, but how can I force Ping and the othermethods in System.Net and System.Net.NetworkInformation tooperate onSubnet2.Station1or Subnet1.Station1 as needed. I think if I can force Ping to work the other problems might be solved. Thanks

I think the framework might have something in the system.directoryservices namespace that can help you find active computers on the network.

A less attractive option would be to broadcast ping the subnets and see who replies.

Thanks for the directoryservices option. I don't think it will work for me because the OS on the POS terminals do not run active directory and as I understand the docs directoryservices only works with Active Directory. When I look on the POS domains for computers I get an error stating that the server is not operational using both LDAP and WinNT.

Will try the ping method barring afurther suggestions.

If you know the names then you should be able to ping them.
If you end up with duplicate names [how is this possible?] then
you might want to ping them by the IPAddress.

I will not know the names. They are user programmable. Is there a way to use the workgroup and name to determine the IP address?

Thanks
