Here is my scenario.
1. Expert host is Windows XP SP2 with latest updates, RA
requestor host inviting the expert to a Remote Assistance
session over the public Internet is Windows XP Home with
latest updates.
2. Windows XP Pro SP2 Expert Host is a follows:
a. Windows firewall disabled
b. In System > Remote tab, Allow Remote Assistance
Invitations to be sent from this computer is checked. After
clicking the Advanced button, the Allow this computer to be
controlled remotely checkbox is unchecked. Invitations is set
to 30 days.
c. In System > Remote tab, Remote Desktop is unchecked.
d. Windows XP SP2 expert host is in private Class C address space
behind a NAT enabled router. UPnP is not enabled on the
router. Port 3389 is forwarded to the Windows XP SP2 Expert
host. ISP connection is cable modem.
3. Windows XP Home RA requestor host is as follows:
a. Windows XP Home host is configured to allow Remote
Assistance invitations to be sent.
b. Windows XP Home host is in a Class C private address
space behind a UPnP enabled, NAT wireless router. Port 3389
is forwarded to the Windows XP Home host. ISP connection is
ADSL. ADSL modem is configured as a transparent bridge.
c. Windows XP Home firewall is enabled and Remote
Assistance firewall exception is checked.
RA Session Initiation is as follows:
1. Windows XP Home host invites by sending a RA file to the
expert via file transfer through Windows Live Messenger.
2. Expert receives this file and changes all occurences of the
Private Class C (i.e. 192.168.1.x) addresses of the RA requestor
host to the Public IP address of the RA requestor's router.
3. Expert executes the modified RA requestor's file.
Result: Expert can still not connect to RA requestor host
machine. Error is as paraphrased ... cannot resolve host
computer name.
Why can the Expert host still not connect to the RA requestor
host?
