re:Connection timed out...
Connection timed out<br>
<br>
A connect or send request failed because the connected party did not properly respond after a period of time. (The timeout period is dependent on the communication protocol.)<br>
<br>
Check the obvious first: check that the destination address is a valid IP address. If you used a hostname, did it resolve to the correct address? If the hostname resolution uses a local host table, it is possible you resolved to an obsolete address. Can you ping that hostname?<br>
<br>
Do you have a router configured? Is the router up and running? (You can check by pinging it, and then ping an address on the other side of it.) Try a traceroute to the destination address to check that all the routers are functioning.<br>
<br>
Check your subnet mask. If you don't have the proper subnet mask, your network system may treat a local address as a remote address (so it forwards addresses on the local subnet to the router, rather than broadcasting an ARP request locally), or vice versa.<br>
<br>
