Thanks Stefaan I'll try it out tonight. -----Original Message----- From: Stefaan Pouseele [mailto:stefaan.pouseele@xxxxxxx] Sent: Thursday, June 05, 2003 3:51 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: Remote Assistant behind ISA Hi David, for some info about how Remote Assistance works, check out: - http://www.microsoft.com/windowsxp/pro/using/howto/gethelp/remoteassist/default.asp - http://www.microsoft.com/technet/treeview/default.asp?url=/technet/prodtechnol/winxppro/maintain/rmassist.asp 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 -----Original Message----- From: David V.

The ISA was switched in teh protocol rules "allow all ports" for Domain Users, and the RDP - TCP - port 3389 outbound was already created. -----Original Message----- From: Dan Gabbard [mailto:intellihome@xxxxxxxxx] Sent: Thursday, June 05, 2003 3:37 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: Remote Assistant behind ISA Create a protocol definition for RDP - TCP - port 3389 outbound.

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?
