Topic: VPN Error 629

[iy houng]

We try to connect Windows98 computer to E-smith 4.1.2 Server through dial-up networking;

  ERROR 629: You have been disconnected from the computer you dialed

Search solutions from e-smith bulletin, still none found. The e-smith server is working correctly. Configuration allows for remote acess, evey settings Public (just for testing now), PPTP clients 2. Using Putty can reach e-smith, web pages can be viewed. But the VPN won't log in. Check win98 network setting, Microsoft VPN is there and enabled, 128 bit security is there too (from IE5.5 about). Check microsoft knowledgebase, disble "Required Encrypted Password", same error. Double check user and password, use admin, root etc, none work. It always stopped at the Error 629 message, never log in.

Any suggestions? Thanks.

Have you looked at /var/log/messages ? This is where the pptp stuff is logged.

To be sure that your PPTP client is using 128-bit encryption, look at c:\windows\system\ppmac.vxd check the properties-> version -> internal name
It should say something like 'PPPMAC (US/Canada Only, Not for Export), this is 128-bit encryption. I got this from article Q104292 in the MS knowledge base.

Thanks for your help.

We look at /var/log/messages, there is nothing in to log file containing pptp. We reformat and re-install windows 98 on a new harddisk, the error message become;
ERROR 751: The remote computer refused the VPN connection.
We look at Microsoft ID Q104292 per your suggestion. Download 128bit security update, after installing download the pppmac.vxd file was rename to pppmac.40. We check the dial-up network Connection, Settings, it did present an 128 bit check box. Try again, the same ERROR 751. Out of desperation we try changing all the check boxes on dial-up connections; encryted, compression, VPN etc.., with known valid user names and passwords. Nothing works. Could that be the problem is on e-smith server, somehow it refused VPN. The PPtP client was set for 2, all other remote settings are Public. Whatelse can we try ?

At this point we check the last log before testing VPN;
[root@e-smith /root]# tail /var/log/messages
.....

May 21 13:53:40 e-smith kernel: PPP line discipline registered.
[root@e-smith /root]#  

Now we test VPN from a win ME machine, make sure settings with Required secure VPN and Only accept 128 bit Encryption. click Connect;

ERROR 751, The remote computer refuse VPN connection. Please try again.

After the refusal, we check log message on e-smith server 4.1.2, the messages
did not change. It was the same as before the refusal. We suspect the VPN connection did not reach the e-smith. However it works on Win ME Telnet and Putty. The Ping was ok. Any further suggestions ?

[Lloyd keen]

So it appears that you've gone from an Error 629 to Error 751 now. Try unchecking the "Require Data encryption" checkbox. Have you tried logging on as different users. Have you tried hitting the local interface as opposed to the external one? Try recording a logfile on the client - go into network settings and double click "Microsoft Virtual Private Netorking" adapter. Click on the advanced tab then scroll down to Record a logfile and change the value to yes (reboot required) The log can be located in C:\windows\pptplog.txt. Maybe try uninstalling VPN altogether. DONT just remove the adapters and protocols - go into control panel - add/remove programs then windows setup and remove VPN this way then re-install the same way. There is another post somewhere describing how to check that the client has 128 bit encryption installed, can't seem to find it though. It may pay to check that as well. Other than that ??????

Hi

I have E-Smith 4.1.1 server and i tried to connect to this server from Win98 using Dialup connection and VPN with PPTP but i am also getting the same error 629.

I had installed PPTP and setup VPN on winNT4.0 workstation which in the same LAN of E-Smith. And when i try to connect to E-Smith from LAN using PPTP i am getting

Error5: Access is Denied

And when i check the more info button it says that

A possible cause of this error is that the connection was rejected by the remote computer because the remote computer exceeded its client license limit..but i am the only guy who is trying this one and i had add 5 licenses in PPTP.

I also checked up in WinNT log file but it did not give any info regarding this.

Any suggestions....

After making sure I had the 128 bit encryption installed on the client and trying all night to find a problem I upgraded to version 4.1.2 and was able to establish a connection. Now I have to figure out why I cannot browse the network
