vpn connection ok but cant find terminal server ?

Hi,

I have a remote user connecting to LAN using PPTP from WinXP home.
Connection established ok and they are allocated an IP on my subnet. Server
hosting RAS is 2003 standard.

User then launches remote desktop over 3389 to connect to terminal server
using IP address but can never find host (server too busy or not found type
error etc ... )

my testing:
- as suggested above user is allocated correct IP and is connected ok (i can
see in RAS)
- user's "default gateway on remote network ticked" on pptp adapter
- user cannot ping terminal server ip once conneted over pptp
- user cannot "telnet ip 3389" (normally get listening port)
- user cannot ping / telnet on 3389 on any terminal servers on LAN
- deleted MSlicencing key in registry but its not that
- i can connect using users credentials to pptp and terminal server
internally
- externally i can connect no problem as well (from an adsl connection to my
hosting server)
- windows firewall (sp2) disabled on users machine

I dont know what else to test, works fine me me using users settings from
external source. It like something else is blocking but PPTP works fine.

Any ideas ?

Thanks for your time.

Can't ping TS by IP that is the problem. Have you enable IP routing on the RRAS? Is the RRAS multihomed computer? Or use tracert command to see where the traffic go.

Thanks for reply

"Can't ping TS by IP that is the problem. Have you enable IP routing on the RRAS? "

IP routing is enabled. This system work fine for this problem user a few weeks ago. Works fine for myself and other users to date. Works fine when i use problematic users login credentials. Just appears to be be from 1 users machine.

"Is the RRAS multihomed computer? Or use tracert command to see where the traffic go."

RRAS host is not at a multihomed computer. I have not trid tracert yet (will give it a go asap).

I get the feeling that this is a problem with users machine, but dont know what.

Thanks for your time
