error when using ping - destination unreachabe or host is unknown
Posted on 2010-11-17
Hello guys and thanks as always for your time and expertise.
Here's my scenario which caused me to ask this question, I was trying to install an application from a shared folder on a server. I had three win7 clients and one winxp client (although please not this problem occurs on winxp systems as well.) On the winxp client, I could connect to the server and everything went fine.
On the win7 clients, I couldn't access the server. Please note I was able to ping all the other servers in this site except the one I needed. The server is question is serer 2003 sp2. I checked all of the relevant network settings and they were all good. I ran the troubleshooter on win7 and it said everything was confirmed right. However, when I tried to ping the server from the win7 clients, and sometimes from some of my xp clients, I get the destination unreachable or host is unknown error.
ok, so after being very frustrated, I pinged these clients from the server and then bang - problem fixed. I just want to understand what happened here. Again, the problem was fixed after I pinged the clients from the app server.
Did this ping from the server add the correct mapping to the arp table which fixed my problem. I just want to know why the ping from the server fixed this issue.
Anyway, thank you for your time and input.
