i'm getting the 'could not resolve DNS on remote computer' (close
verbage). i
am trying to test sending and receiving a remote assistance request within
the pc's in my home.

here's my setup...

1) requesting pc on XP Home SP2, receiving request is pc on XP Pro SP3
2) no problem creating the request via email
3) no problem receiving the req
4) all my pc's sit behind Linksys router
5) tried forwarding port 3389 for both pc's in router
6) viewed 'invitation' in notepad to check IP addresses
7) enabled all (i think) services and Firewall exceptions
8) no matter what changes i tried this is the message ALWAYS rec'd...
A Remote Assistance connection could not be established because the DNS
name
of the remote computer could not be resolved

i have also tried Remote Desktop to no avail also from the XP Pro pc to
the
Home pc. i would truly appreciate if someone could turn on the lights for
me!!! ;-) thanks much...

Over a local LAN use the file method for the invitation for RA.
This may help...

TeamViewer also can be used IP to IP over a local LAN. Run
TeamViewer on the PC, the so called Novice PC (RA parlance), you
want to remotely control and go to "Extras > Options > General" and
check the "Accept incoming LAN connections" checkbox at the bottom.
If you want that PC to only accept LAN connections (and not
connections from the public internet) go to the "Advanced" tab and
check the "LAN connections only" checkbox. Call the PC by its LAN
IP from the so called Expert PC (RA parlance).

FYI, you can *NOT* use Remote Desktop to remotely access/control a
XP Home PC. You can use Remote Desktop to remotely access/control a
XP Pro/MCE PC.

Al, thanks for the post and fyi.

at this point, i'm thinking that the fact i have both of pc's
sitting behind the same router is what is creating the problem.
even tho each pc has its' own ip address the router has one ip
address and i think that is my point on contention. but as
witnessed by the success of TeamViewer software i know there has to
be a way to succesfully test RA within my home config. i think
there might have to be a mod in the RA incident ticket or something
i'm still not doing correctly in my router setup.

Still trying tho...

When I use the procedure from the page I pointed you to on my
wife's XP Pro desktop the resulting invitation file looks like this.

<?xml version="1.0" encoding="Unicode" ?><UPLOADINFO
TYPE="Escalated"><UPLOADDATA USERNAME="Linda"
RCTICKET="65538,1,192.168.1.33:3389;norman:3389,*,TQp+Od3cqZlhJaESr/8eOx5jVAzSEvoh6sq9ylmx2G4=,*,*,fK9Nyod0pGddhbKpl5MD82MnerQ="
RCTICKETENCRYPTED="0" DtStart="1239449414" DtLength="60"
PassStub="" L="0" /></UPLOADINFO>

The RCTICKET field contains the LAN IP address of her PC (the
Novice) that is used by my RA client (the Expert) to call. So if
the RCTICKET field does not contain the corrrect IP you can modify
it manually. See this for more information about the invitation
file format.

In my case both the expert and novice PCs are behind my NAT router.

thanks again Al. yeah the only difference that i see in your tix
from mine is that you do not have a 'single' IP address for your
router followed by the unique IP address from that particular PC.
so i wonder why that is when we both share similiarly designed home
networks. the only other thing that comes to mine is i'm using
OPENDNS.ORG as my static DNS 1 and 2.

question...if you got to www.whatismyip.com do you get the exact
same address for each of the PC's behind your router? this is what
i get and this is also the first IP address listed in my RA ticket
followed by the unique address and then the unique name of the pc
(as i posted earlier).

i'm really curious as to why our RA tix are different? thanks...

You would see the external IP address of the router for every

exactly. so why is this external/router address included in my RA
tix and not Al's?

Sooner Al clearly stated both machines (in the given example) were behind
the NAT router. ;-)

An old post of Sooner Al's...
http://groups.google.com/group/microsoft.public.windowsxp.work_remotely/browse_frm/thread/740b8e9586f4f8b9

You are editing the invitation so it contains the private LAN IP, correct?
And your DNS for each computer is automatic (or set to) the NAT router?
(I see the second is not true.)

Set the DNS on the NAT router (if you must) and pass all the machines to it
for DNS searches.
