Configured VPN access and can connect to VPN on internal network. Problem comes up when I try to connect from the Internet. I get an Error 800: Unable to establish VPN connection. If I check logging on ISA server I can see PPTP port 1723 being opened from the client and then closed without any errors. I also see the client opening HTTPS ports. Got no idea why it would want to open HTTPS when connecting via VPN. I can also telnet toport 1723 from the internet. Any help will be appreciated. _____________________________Johan Grové Senior Technology Architect Cellphone 0825227200 MSN: johangrove@hotmail.com www.eclipse.co.za Post #: 1 Featured Links* RE: VPN Error 800 Unable to establish the VPN connection - 23.Jan.2008 2:54:02 PM elmajdal Posts: 6022 Joined: 16.Sep.2004 From: Lebanese in Kuwait Status: offline quote:Installed ISA 2006 on a domain controller No NO NO NONO Never Install a Firewall on a DC !!

connection to the SBS Server and you received an error 800 message. If I have misunderstood your concern, please do let me know. This issue occurs because the Configure E-mail and Internet Connection Wizard (sometimes known as CEICW) http://www.tech-archive.net/Archive/Windows/microsoft.public.windows.server.sbs/2007-01/msg00677.html does not enable PPTP connections through the Microsoft Internet Security and Acceleration (ISA) firewall. 1. On the Small Business Server 2003-based server, click To Do List in the left pane of the Server Management console. 2. Under Network http://www.mombu.com/microsoft/isa-server-vpn/t-isa-2004-vpn-error-800-on-client-machine-275215.html Tasks, click Configure Remote Access. 3. Click Next, click Enable Remote Access, click to select the VPN Access check box, and then click Next. 4. Type the fully qualified public domain name (FQDN) of your server, click isa server Next, and then click Finish. 5. When the wizard is completed, click Close. After doing that, go to the client and establish the VPN connection to the SBS Server, you can refer to this KB article for more information: How to configure a VPN connection to your corporate network in Windows XP Professional http://support.microsoft.com/default.aspx?scid=KB;EN-US;305550 Will you be able to establish the VPN connection to the SBS Server successfully? If the VPN is working fine, isa server 2004 it appears that the problem doesn't reside at the SBS side. We may need to perform a further investigation. Based on my experience, error 800 is caused by a router that has outdated firmware in some cases. Please check this KB article to see if your hardware router has applied the latest firmware. You may contact the vendor of the hardware router for more detailed information. Error Message: VPN Connection Error 800: Unable to Establish Connection http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q319108 To check if the VPN is blocked by the hardware router, we always use the PPTP Ping to test if 1723 port and GRE protocol are allowed to pass through. To do so: a. Please run Pptpsrv.exe on the server side. b. Run Pptpclnt.exe [ServerNameorIPaddress] on remote client. c. When prompted by Pptpclnt.exe, type some text to send to Pptpsrv.exe, and then click Enter. d. You will see the text received at the host running Pptpsrv.exe. Then you will see five GRE packets sent from Pptpclnt.exe and received at Pptpsrv.exe. Provide me with the output for reference. NOTE: PPTP Ping tools (Pptpclnt and Pptpsrv) exist in Windows XP support tools. For your convenience, I have attached the file within this reply. NOTE: You should stop the Routing and Remote Access service on the RRAS (VPN) server so that PPTPSRV can bind to port 1723 B
our Hints: 1 28th July 14:28 fuochi External User Posts: 1 ISA 2004 VPN error 800 on client machine Hello I have a Windows 2003 Server with ISA 2004 installed and I have an other server which is a SBS 2003 server. When I configure the VPN on the ISA server I got a error 800 on the remote client machine that want to connect to VPN. On the ISA Server the RRAS service is disabled, but enabled ont the SBS 2003 Server. Question : what must I configure so the VPN on the ISA Server is rooted to the SBS 2003 Server : - is it a DNS configuration error ? - is it a RRAS configuration error ? - is it a DHCP configuration error ? thanks in advance fuochi sponsored links « Previous Thread (l2tp-in-back-to) | Next Thread (isa-server-with) » Thread Tools Show Printable Version Email this Page Display Modes Linear Mode Switch to Hybrid Mode Switch to Threaded Mode Rate This Thread You have already rated this thread Copyright © 2006 SmartyDevil.com - Dies Mies Jeschet Boenedoesef Douvema Enitemaus - 666
