L2TP connection problem!

Hi
I configured my VPN server with L2TP, SSTP connection type.
The problem :
SSTP works fine but L2TP connection type can't reach the VPN server.
My Settings :
1. LabTop, Windows XP, The Server
2. PC, Windows 7, The Client
Both of them connected to the same router (which I think this is the problem).
I have to edit my registry to connect to any L2TP VPN and it's working with other than My Server "Disabling IPSec policy: prohibitipsec DWORD 1" and When I allow L2TP without IPSec in my VPN server I can't connect to any other L2TP server!
What to do?
P.S: Do I need the Dynamic DNS Address, Pre-shared key, username and password to connect?
Thanks in advance.

Guys! Are you kidding????
Here is a step by step manual how to run the server and even what to put in the host name field on the client. Read it at last!

In my country L2TP/IPSec blocked but L2TP without IPSec working fine.
This Tutorials for L2TP/IPSec!!!
and when I allow unencrypted connection I can't connect to any other unencrypted server including main.

Again! Read the documentation. If you ignore it, at least read what windows show you...

Windows 7 does not support L2TP without IPSec by default. You need to disable IPSec in the registry. Or you need to use special client.

I already done that but the problem is no connection on the same computer to any other serve.
And no connection from other computer on the same router to my server but there is connection to other than main.

Correct your English as it is impossible to understand from/to you are trying to connect.

I'll bare with it!!
On my laptop (the server): I can't connect to my or any L2TP server if I enabled (Raw L2TP)
On my PC (the client)on the same router: I can connect to any other L2tp server except main (with Raw L2TP enabled).

Why? You should only have done it on the client PC.

I didn't try that. (P.S. IPSec blocked in my country)
Q: Can I be a side of the network (File Sharing, Gaming,....) with just the server app or I have to connect to it as client?

I can not understand your question.
More to say I do not understand what topology you are trying to implement.

My bad!
The PC on the same router just to test the connection cuz like I said : IPSec blocked, so I want to know what setting I have to give to my Clients.

for what you wrote:
yes, the server I'm running is the main files storage server to share it with Clients.

Take my advice - use SoftEther client.
Good luck.
