| reply to rjs1003 Re: NIGHTMARE - AT&T Global Network Client + Links
Short version: In WinXP I added key EnablePMTUDiscovery set to TRUE & rebooted based on: »support.microsoft.com/?scid=kb;en-us;Q314053 which was pointed to by this guy: »dev.remotenetworktechnology.com/···hole.htm who has some good info on his other pages too. BTW, many of the other optional TCP registry keys were already set by some program (ATT NetClient suspected).
Detail: OS: WinXP, with firewall ZoneLabs Integrity Desktop v3.5.175.057. Private LAN connected to LinkSys WRT54G with FW level v1.30.7 Jul 8 2003, with TCP & UDP port forwarding of 500-500, 5080-5080, and 3389-3389. Also enabled VPN PassThrough IPSec & PPTP. ATT Global Dialer: AT&T IPSec Application version 5.05.1
Before adding the EnablePMTUDiscovery key, Remote Desktop was giving me the black screen with cryptic message "connection to the remote computer was broken" after ATT VPN connections were complete. I also couldn't FTP files or network folder browse to all systems.
Note I keep hearing that ISP's are reconfiguring router network settings to limit virus activity, which may be adding to end-users network woes.
Hope this helps all you folks. Good luck! |
