dforionstar Posted February 3, 2009 Share Posted February 3, 2009 I have two XP Pro SP2 partitions. I use C: primarily, and E: for emergencies and testing. On E: my VPN connection works fine. However on C:, I continually get "Error: 800 Unable to establish connection" .I am able to ping the VPN host from the command line, and the MS IPsec Diagnostic Tool confirms the host is reachable. But I get Error 800 when using the VPN Connector, whether I use Comodo 2.4 firewall, or Windows Firewall.I suspect the VPN connector is not dialing out, or I have an error in the registry and would like to be able to rebuild/reset the default XP VPN settings if possible. I have the original XP Pro install CD.I always use a laptop and wireless access.Any assistance is greatly appreciated!=============================Here is the MS IPsec Log:-----------Local Mode Diagnosis:Start - 2009/02/03(14hr:58min:55sec)-----------Log Location: C:\Documents and Settings\Administrator\Application Data\IPSecureLogs\LocalMode2009-02-03(14hr-58min-55sec)Local IP: xxx.xxx.xxx.xx, Remote Machine: 142.103.203.46SystemInfo:--Passed: System information(software, hardware,active processes, active network connections) collected.

anthonyaudi Posted February 5, 2009 Share Posted February 5, 2009 The log files suggest that the you are able to see the host but it seems that nothing is configured on the host side.It looks like theres no way of your client machine to authenticate to the host thats what the log is suggesting.From what I can understand about it Link to comment Share on other sites More sharing options...
dforionstar Posted February 6, 2009 Author Share Posted February 6, 2009 Thank you anthonyaudi.When I log off from the C: drive installation that the log was taken from and log in on the E: drive XP installation, I am able to connect to the VPN network with no problem. So the host must be configured.I suspect my install on C: is missing some registry settings or required files to be able to commuicate with the VPN.I assume the MS diagnostic tool is not relying on the settings/files that the VPN requires.Is is possible to rebuild the Registry settings that all VPNs will require?Thank you.

anthonyaudi Posted February 6, 2009 Share Posted February 6, 2009 I am assuming you use the same programs on the C and the E to try and connect VPN?Did you try just reinstalling whatever program you are using on the C to see maybe if that fixes your problem?As far as looking for orphaned registry files that might be causing you problems I'm not sure how to go about doing that but generally if you would reinstall the program you use to connect vpn and reinstall it it normally deletes all the reg files and will rewrite them when you do your install.Does the VPN use a particular port that you might have blocked in your firewall?Do you have windows firewall that is enabled and you did not add that port as an exception? (I know that these scenarios are unlikely because you can connect via the E drive but there has to be something that is blocking you from reaching the host)Did you assign a static IP on the tcp ip settings of the c drive?I know where I work anything I want to do when it concerns VPN///VNC cannot be done via wireless because it is blocked by my router.Try reinstalling the programs you use to connect via VPN and try on a wired connection just for the heck of it Link to comment Share on other sites More sharing options...
dforionstar Posted March 9, 2009 Author Share Posted March 9, 2009 Thank you for your advice.I agree, reinstalling should reset the settings.I am in the process of re-installing what I can. The Windows repair should have re-installed the RAS settings. I don't use any 2nd or 3rd party software to connect, only the built XP network connections. If the XP repair didn't reset what was causing the issue, then I am assuming it is a user setting, somewhere.I am in the exhaustive process of comparing registry entries between the working and non-working systems. I have noticed some differences in Broadcom LAN adapter entries and the versions (though changes should be minor), I used are not the same so that is one consideration. I plan to uninstall the Broadcom drivers, which will insist on re-installing upon the next re-boot. Then I have to investigate WAN Miniport (L2TP) settings.I don't know much about networking. I only use the Wireless adapter on my notebook, but it is possible the Broadcom driver install changes some settings. Link to comment Share on other sites More sharing options...
