When I connect two pcs then I got the message that The network path was not found... So, tell me the solution of this problem.

This is a very generic message that isn't very informative. Basically, it tells you that the operating system couldn't find the other computer.

First, determine the IP address of both computers. Do this by clicking "Start | Run" and entering "CMD". Click OK. A "command window" will open.

At the command window, type "ipconfig<enter>".
something like this will appear:

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . : something here
IP Address.. . : 192.168.1.100
Subnet Mask.. . : 255.255.255.0
Default Gateway.. . : 192.168.1.254

The numbers may vary.

If you don't have something like this, then you haven't obtained an IP address. In that case, I'll need to know how you connected the two PCs together.

If you do get something like this, take the IP address of the "other" machine and type "PING [ipaddress]<enter>" where [ipaddress] refers to the ip address of the other computer (the computer you're trying to connect to).

If you see "Request timed out", then the two computers aren't communicating.

If you see "Reply from [ipaddress]: bytes = 32 time<1ms TTL=128

or something like that, then they are communicating and there's something blocking the communication (maybe Windows Firewall or another firewall program).

Check back here with the results and we'll try to help you further.

Dear Perito,


Thanks for the reply...

Actually I have other PC and it is also in same network but it can communicate with that PC but my PC can not communicate from \\<ip add>.

For example...

I have PC1, PC2 and Sever1. All are in same network and also configured same with firewall rules. OK...

PC1 can ping, and communicate with "\\<Server1>" but PC2 can't... then what should be the problem..

Does PC2 have an IP address?

Yes, pc2 has ip address and same configurations as pc1. And all are in same network

Check for a firewall on PC2 -- Turn off windows Firewall. If you have ZoneAlarm or another personal firewall or some Internet Security Suite, turn that off, also.

Try using TaskMgr to locate all elements of personal firewalls and terminate them. Also, click "Start | Run", enter "Services.msc" on the command line and click OK. In the "Services" window, try to locate any running service (Sort by the STATUS column) and stop it. Don't worry, it'll restart the next time you boot unless you set the "Startup type" to "disabled" or "manual".

After you're pretty sure that you've terminated anything that may have block a ping, retry the ping. If it succeeds, then you've got to nail down the program that's blocking the ping.

I would suspect PC2 since other machines can communicate with PC1 and Server1.

Could there be some sort of policy preventing access to Server1? Are any of these PC's/server part of a domain?

In my case there are two networks and I am using toggle switch between them. Like (1) internet (2) local network

In internet network all machines are communicate each other and there is no problem with pc2 or pc1

And my server is in local network. When I toggle my network from internet to localnet that time I am facing this problem

Then no firewall or any other services come to the picture . If some problem in services then internet commination should not work right?

What you think...

This is much more complicated than you led me to believe. I think that when you switch networks, your computer isn't recognized as being authorized so its packets are suppressed in some manner. I'm not sure I can figure this one out remotely.

Another possibility is that your switch is defective.

Check how that networkconnection handles ICMP.

You need to check both computers ip address whether it is configured properly or not then configured in the sequence.

Please do an IPCONFIG /ALL for each of your computers and server and post the information.

1) What OS is the "server"? Is it just another workstation acting as a server or is it an actual server OS?
2) Are you using a router for Internet access?
3) What kind of switch are you using to "toggle" between the networks? Why do you want to "toggle" between the networks?

A router will help to isolate your home network from the Internet by placing it into a network address range that is not visibile from the Internet. So "toggling" between networks can be performed by the use of routing.
