client using PPTP. The Client use the security setting CHAP and MS-CHAP v2. I had read the previous post "PPTP VPN not working with Windows 7. Error 691. Works fine http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/connect-to-vpnerror-691/14fe57c9-4334-4fc7-9597-c3f2b9e28ecd with XP." but no solution were offered. The computer is Windows 7 Ultimate. I had tried ticked and unticked other boxes, stopped the firewalland still no luck. I ran the log (netsh ras set tr * en) and thezipped file can be found in https://cid-af62be706469eb40.office.live.com/self.aspx/.Documents/tracing.zip. Many thanks in advance.

Error 691: Access denied because username and/or password is invalid on the domain. You can try these steps: 1) Verify the logon ID and password are correct. 2) Make sure the Include Windows logon domain check box is unchecked in the Options tab of the dial-up connection's Properties dialog box. 3) Make sure the dial-up connection's security option is correctly configured to use the Require secured password setting. 4) Delete all of the *.pwl files and reboot if you are using win9x. 5) Try another logon ID or create a new Logon ID because the profile may be damaged.

user name and password combination you provided is not recognized, or the selected authentication protocol is not permitted on the remote access server. This worked fine when connecting from Windows XP and Windows 7, but suddenly stopped working when connecting from Windows 8 and http://dascomputerconsultants.com/VPNErrorAnalysis.htm 8.1. Why? Read on for the details, or Click Here to skip the geeky analysis stuff and jump to the answer. Click Here for Press Release Sniffing the glue that holds the internet togetherThat tag line used to be on https://vkelk.wordpress.com/2012/10/28/windows-72008-error-809-l2tp-vpn/ the Ethereal download page, which is now called wireshark. Wireshark is a network sniffer - it captures the data flowing across a network and interprets it into easier to read geek speak instead of hard to read network bits. Normal people vpn error plug things in and expect them to work. Engineering geeks like analyzing why things don't work and figuring out how to make them work. Fortunately for my clients, I'm the latter. Here is the error screen caught with a camera phone: If you have a propeller hat, now is the time to put it on and get the propeller spinning full speed! How it used to workSince it works on other systems, the short distance to diagnosing the problem is often the remote connection comparing what system "Works Great!" does with system "It Doesn't *&*!@#-ing Work", finding where they diverge, and using that as a pointer to further analysis. So rather than analyze one then the other, I think it will make more sense to compare them side by side. That isn't an eye chart - it is a thumbnail. Click on it and look at it full screen or scroll around while you read the analysis. The left side is the sniff that fails, the right side works. The first three packets up top on each trace are the SYN / SYN-ACK/ ACK of a TCP session establishing - 51,52,53 on the left, 30,31,32 on the right. The two traces are mostly the same, up till the highlighted in yellow on both sides. When two systems are attempting to establish a VPN tunnel between them, there is a lot of negotiation back and forth. There are different options for how to encrypt, what key lengths, how to authentcate, if we are compressing data or not, ... and two systems need to figure out how each other wants to talk in order to establish how they will interoperate. Incidently, this is a similar process when you type "https://" into your browser, but that is another story. So that first block on both sides in white background are the same on both traces except for a little bit of negotiation NAK / ACK-ing where I highlighted in yell
default, Windows 7 and the Windows Server 2008 operating system do not support Internet Protocol security (IPsec) network address translation (NAT) Traversal (NAT-T) security associations to servers that are located behind a NAT device. Therefore, if the virtual private network (VPN) server is behind a NAT device, a Windows 7-based VPN client computer or a Windows Server 2008-based VPN client computer cannot make a Layer Two Tunneling Protocol (L2TP)/IPsec connection to the VPN server. This scenario includes VPN servers that are running Windows Server 2008, Windows Server 2008 R2 and Microsoft Windows Server 2003. Update: Also applies to Windows 8.1 connecting to a L2TP VPN running on a Windows Server 2012 R2 Because of the way in which NAT devices translate network traffic, you may experience unexpected results when you put a server behind a NAT device and then use an IPsec NAT-T environment. Therefore, if you must have IPsec for communication, it is recommended that you use public IP addresses for all servers that you can connect to from the Internet. However, if you have to put a server behind a NAT device and then use an IPsec NAT-T environment, you can enable communication by changing a registry value on the VPN client computer and the VPN server. To create and configure the AssumeUDPEncapsulationContextOnSendRule registry value, follow these steps: Log on to the Windows 7 client computer as a user who is a member of the Administrators group. Click Start, point to All Programs, click Accessories, click Run, type regedit, and then click OK. If the User Account Control dialog box is displayed on the screen and prompts you to elevate your administrator token, click Continue. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent On the Edit menu, point to New, and then click DWORD (32-bit) Value. Type AssumeUDPEncapsulationContextOnSendRule, and then press ENTER. Right-click AssumeUDPEncapsulationContextOnSendRule, and then click Modify. In the Value Data box, type one of the following values: 0 A value of 0 (zero) configures Windows so that it cannot establish security associations with servers that
