Re: Weird TCP/IP Problems

I now have a fix for the problem from the OpenDNS folks - my first
message to them must have got lost, since they replied to a second
within 12 hours - this is much more typical of their usual level of
support, BTW.

Basically, you need to create an account for yourself on the OpenDNS
site, register your IP address (they call it registering your
network), and turn off "typo correction" for it. I imagine that they
will be working on providing a less wholesale solution to what must
(IMHO) be a bug in the typo correction code. If you have a dynamic
address, there is a little bit more to it - email me at
"pfletch<at>fletchers<hyphen>uk.com" (editing spam traps
appropriately) if you have problems with the rather sketchy
instructions on the OpenDNS site.

Wow. Just wow.

Why does changing the DNS Server my router uses to lookup domain names screw
up my computer from resolving computer names on a simple home network?

I'm no network guy, but I think that maybe that shouldn't happen.

My crystal ball tells me that you are using OpenDNS as a DNS server
(actually, 208.67.219.40 is one of their server addresses). I am
seeing exactly analogous bizarre behaviour, having recently changed to
using OpenDNS, and have not had a reply to my query to them about it.
It is screwing me up because one of the systems on my local network
can no longer find my mail server (on another local system), because
its address is now being returned as 208...... Please post back here
if you find a solution elsewhere.

I have four computers on my netork, all on the same workgroup, who get their
IP information over DHCP from a Linksys Wireless G router. Two computers are
wired, two are wireless. Simple enough?

I can only ping other computers by using IP addresses (ping 192.168.1.10).
If I type [ ping laptop ], I get this response:

That is not my laptop's IP address. And I have no idea where 207.67.219.40
is, but it's not in my house that I know of. And what does
"domain_not_set.invalid" mean? And what's with the latency of almost 100ms
if it's in my house?

I don't get what's causing this.

BUT -- I can open up Run and type "\\laptop" and I get a folder listing of
shares that are on my laptop. Why can Windows resolve \\laptop but not ping
laptop?

Is this a problem with my router or computers (all four of them?!) or just a
setting?
