Some details about the issue.
I'm trying to connect to my client's network using VPN Client version 5.0.07.0290. The user authetication is done by providing RSA SecureID token value. After entering proper credentials, the client window gets struck at 'Securing Communication Channels...' message in status bar and reports 'Reason 442: Failed to Enable Virtual Adapter' error after few mintues. I have confirmed that this version works for other people in my team , so I'm guessing it has something to do with my system settings than the client itself.
Below are the trobleshooting tips that I have already tried.
1. Uninstall and Reinstall the client.
2. Enable WinXP SP2 compatability for ipsecdialer.exe and vpngui.exe.
3. Clicking 'Diagnose' on the Citrix Virtaul Adapter connection in Networks and Sharing centre, reports no issues.
4. Enabling Network sharing for Local Area Network and disaling Wireless Networks
I'm running Windows 7 64 bit Enterpise OS.
Appreciate any suggestions to resolve this issue.
OK, things look much better after a good vacation, always!!!
I tried to connect today by reinstalling the client after a weekend shutdown (I don't believe the cold reboot stuff, but hey, worth a try! ) and it did work. The only change I did today was to disable the Wireless Connection adapter in Networks Connections. I'm not sure whether that fixed or not cause I had tried that already. Anyway, below is my current configuration which is working for now!
1. Below executables are running in the XP compatability mode.
cvpnd.exe, VAInst64.exe, vpngui.exe
2. Local Area Connection is allowed for 'Sharing'
3. Registry is updated with below entry.
HKLM\System\CurrentControlSet\Services\Tcpip\Parameters /v ArpRetryCount /t REG_DWORD /d 0 /f
4. Wireless Connection is disabled.
Thank you all for the responses.
Solved! Go to Solution.
Just to add here that this solution will work also on WIN10 64.
1- Login by Administrator.
2- run>cmd>cd\>reg add HKLM\System\CurrentControlSet\Services\Tcpip\Parameters /v ArpRetryCount /t REG_DWORD /d 0 /f
3- run>regedit> go manually to: HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Services>CVirtA
Edit: DisplayName value to: Cisco Systems VPN Adapter for 64-bit Windows (only)
This will solve CISCO VPN client 5.x and Aventail VPN on WIN10 64bit.
we are able to connect in Lan network by using following steps,but we are unable to connect through datacard.
This also worked.. thanks a bunch
Removing the OEM Variable and leaving the Cisco System VPN
Restarting VPN Client --> Boom it worked
When I get this error, i've noticed that the virtual adapter fails to enable. If I manually enable the adapter and then retry the VPN connection, it always works. I'm trying to figure out why the VPN client no longer automatically enables the connection. You may want to try enabling the adapter manually and reconnecting. Workaround, not a solution....yet.
Guys I was having the same problem, and disabling the Internet Connection Sharing did the trick.
If the connnection you are using to go out to the Internet has ICS enabled, this problem might occur, You don't have to disable any wireless adapters, in fact right now my LAN is disconnnected and I am using wireless to go out (and this had ICS on).
I had the same problem. Here's what I did to make it work:
Start-> Run-> services.msc *Enter*
Look for Internet Connection Sharing (ICS) in the list. Doubleclick.
Change startup type to Disabled.
Below Service Status, press Stop.
Then press Ok, to close dialog. Restart VPN client, and it worked again this time. Woohoo.
