Topic: IPSec and PPTP

[Neririn]

For some reason, some and only some, of my dial up VPN users on XP, can not see nor ping remote boxes across the IPSec tunnel. For others it works just fine.  For those with the problem, they can VPN into the respective boxes, and see that 'local' lan, but can not see anythig via the tunnels.

Has anyone experienced anything like this?  Any help would be hot.

Hi Neririn,

I'm seeing this too for XP users but Win98SE users work fine. I'm looking at this issue this weekend and will get back with any successes.

No-one else ?

Hi Neririn,

OK, what fixed it for me .....

On SME server-manager
1. Configuration -> Workgroup, tick the box marked Workgroup and Domain Controller.

On the XP machine
2. Make sure XP users use the same username:password on their XP machine as is known to SME for email/share access.

On the XP machine
3. In the PPTP connection properties
  (a) Security Tab - tick Automatically use my windows logon name and password
  (b) Networking Tab -> TCP/IP -> Properties -> Advanced -> WINS  add the SME server local IP address and tick Enable Netbios over TCP/IP.

Let me know if it helps.

Neririn,

When ping fails, does name/host resolution fail to resolve, or do your pings get 0 replies?

I have seen similar problems with XP and pptp.  If this is your problem, as stated in this forum use your SME as the WINS server, or define your AD DNS servers and domain prefix on all XP pptp client TCP/IP configs...this work for my agency.
