To detect and avoid network problems, do the following:
C:\>PING 127.0.0.1
Alternatively, you can PING the same server name you are trying to connect to or resolve (e.g., BROKERSERVER). For example:
C:\>PING BROKERSERVER
"PINGing" is a way to test connectivity. PINGing sends an Internet Control Message Protocol (ICMP) packet to the server in question and requests a response. It verifies that the server is running and the network is properly configured.
If the host is unreachable, there is a network problem and you should consult with your network administrator.
If you get a time-out, it may be your network configuration on the client workstation, proceed to Step 2.
If the server is reachable, proceed to Step 4.
