Hi David,

for some info about how Remote Assistance works, check out:

Because the Helper must connect to the person who is being helped on TCP
port 3389 (the same socket used as for Terminal Services), it depends on
which party is behind a NAT or Firewall device. I never tries it, but I
think that if only the Helper is behind an ISA server, it might work.

HTH, 
Stefaan

I'm sorry, I forgot to put in.  The ISA was switched in teh protocol rules
"allow all ports" for Domain Users, and the RDP - TCP - port 3389 outbound
was already created.

Create a protocol definition for RDP - TCP - port 3389 outbound. Then create
protocol rule using the new definition.

Hi everyone,
    I was helping out a friend last night using Remote Assistant (pretty
kewl tool)

Scenario:

My Computer -- ISA -- internet -- NAT - My Friend's Computer

    I wasn't at the first time we connected were successful to establish a
session, I've passed through some google news articles and found out, that
at least on computer must in front of a NAT or Firewall to allow the Remote
Assistant to work.

My Computer -- internet -- NAT - My Friend's Computer

    Now it worked!  I know Remote Assistant uses a share version of Terminal
Services but am I missing a port on the ISA server that is not allowing me
to gain access to my friends PC?  or is it just confused about have both a
NAT box and a firewall in the mix inhibiting the session to connect?
