I had a strange thing happen the other day.

When I attempted to ping by hostname, the destination was unreachable.

When I was able to determine the IP address of said hostname, and ping that, success.

This operation was just seconds apart.

This seems odd to me.

I suppose it could be a host, firewall or router configuration issue. What is w4351611? Scott.

This is from a work network. w4351611 is the hostname of the device I was pinging.

I was re-imaging the device and attempting to VNC into it from my device over the network. Normally, this is not an issue, and works fine, even at a remote location. In this case, I was in the same building on the same subnet.

VNC via the IP address was successful. After reimaging was complete, VNC and our normal Dameware remote client connection via the hostname was also successful.

At the beginning of the reimage process, we use VNC because Dameware is not yet present on the device. Once the imaging process reaches a certain point, we can use Dameware to monitor the process.

In that case it sounds like the DNS had not yet propagated when you first tried to ping. Scott.
