Cisco VPN on Vista (The Fun will never end)
by admin on Apr.04, 2007, under Networking, Systems, VPN, Vista
Well after some limited users were using the Cisco VPN Client 5 beta it worked at first then we had some more problems with intermittent connection problems.
Last post here
Cisco has just released the official Client 5.0.00.0340 which is supposed to fix most issues with Vista. Remember you cannot use the installer shield version in Vista only the MSI. We will be testing this version once again. There are also some workarounds Cisco posted if you continue to have problems.
Workarounds for Vista:
Error 412: The remote peer is no longer responding
Upgrade local NAT device’s firmware
If this is not possible, switch to TCP
If this is not possible, use the following keyword in connection profile (*.pcf):UseLegacyIKEPort=1CAVEAT: If you are using Domain Isolation customer will not be able to use the UseLegacyIKEPort
keyword as this conflicts with Microsoft�s domain isolation.Error 442: Failed to enable virtual adapter
Open Network and Sharing Center
Open Network Connection Manager
Enable the virtual adapter (�Cisco VPN Adapter�)
Right-click on it and select �Diagnose�
Select �Fix��If this doesn’t work
Run the following from �cmd’:
reg add HKLM\System\CurrentControlSet\Services\Tcpip\Parameters /v ArpRetryCount /t REG_DWORD /d 0 /f
RebootNOTE: If customer has UAC enabled, s/he must run �cmd� as administrator.
Error 1721 (At install time.)
Client does not support 64bit.

hi there,
my sister had error 442 on her vista-notebook. we shut down the firewall and stuff but nothing helped.
but then we got it: there is this message that pops up in vista when u wanna do stuff like installing a program. the screen gets darker and u get basically asked “do u really wanna do this”. we got rid of that annoying message (it is a box you have to untick in your user-settings) and cisco vpn connects fine since then

Yeah I believe the setting you are talking about is under Control Panel -> User Accounts -> “Turn User Account Control on or off” -> Uncheck the “Use User Account Control (UAC) to help protect your computer”
This is a very annoying setting on by default in Vista. I believe the people having problems unchecked this box but I should have them double check. Thanks for the Comment.

That you for the recommendation, I will have to try:
Run cmd as Administrator and execute the following command:
reg add HKLM\System\CurrentControlSet\Services\Tcpip\Parameters /v ArpRetryCount /t REG_DWORD /d 0 /f
