Cannot connect with hostname CAN connect with IP address

Post by glen4cindy »

The subject says it all.

This is concerning the same server from the same laptop computer, running the latest version of UVNC.

It is only happening from THIS laptop, no other PC in my home LAN is having this problem.

The laptop having this problem is a Windows 7 Home Premium 64bit machine.

Any help would be appreciated.

Thanks,

Glen

Can you ping the other machine by host name? By IP address?

When you say host name, are you using a fully qualified DNS name or the NetBIOS host name of the machine? If the former, are those fully qualified DNS names resolvable on your internal network?

Can you telnet to the other machine on port 5900 (or whatever your VNC port is)? By IP address? By host name?

Are

Is there some security software or other possible changes to your Windows 7 machine's hosts file?

I think it would be the Netbios host name because it's like: dadspc, momspc, kidspc, etc.....

Cannot ping by that name, but I can ping each by IP

Have not tried to telnet to each one, I can try that.....

I've not tried the FQDN...I'm not sure what that would be on a home network.......

No security software or hosts file changes....

I think we've got the answer then. You wrote "It is only happening from THIS laptop, no other PC in my home LAN is having this problem. The laptop having this problem is a Windows 7 Home Premium 64bit machine."

My bet is that te Win7 laptop is just not on the same Windows Workgroup (or domain) as the other machines!

The default workgroup name in Windows 7 has been changed to WORKGROUP. In Windows® XP Home Edition, the default workgroup name is MSHOME. If you upgrade a computer running Windows XP Home Edition to Windows 7, it will keep its existing workgroup name. However, new computers with Windows 7 can have a different workgroup name than the other computers on your network. With different workgroups, it takes more time and effort to view all of the computers on the network.
