Reason 442: Failed to Enable Virtual Adapter - Windows 7 64 bit

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.
Thanks,
PVNSKC
Update: 9/7/2011
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.

Hi,
Duplicate IP Address Triggers Error 442 on Windows 7 and Vista
The following error "Reason 442: failed to enable virtual adapter" appears after Windows 7 and Vista reports a duplicate IP address detected. Subsequent connections fail with same message, but the OS does not report a duplicate IP address detected.
To work around error 442, do the following steps:
Step 1 Open "Network and Sharing Center".
Step 2 Select "Manage Network Connections".
Step 3 Enable the Virtual Adapter ("VA"—Cisco VPN Adapter).
Step 4 Right-click on Cisco VPN Adapter and select "Diagnose" from the context menu.
Step 5 Select "Reset the network adapter Local Area Connection X".
If this procedure does not work, run the following command from cmd:
reg add HKLM\System\CurrentControlSet\Services\Tcpip\Parameters /v ArpRetryCount /t REG_DWORD /d 0 /f
Then reboot.
This resolves the issue until the OS reports a duplicate IP address again. Follow the preceding steps to resolve it again.
If that doesn't work, you might have UAC enabled. If so, you must run cmd as administrator and repeat the previous registry workaround.
NOTE: You mentioned step 4 already, try the whole sequence again, if the steps does not work then try the registry key.
Hope this helps,
Sian

Vista, Cisco VPN Client 5.0.01.0600 "Failed to enable Virtual Adapter"

Four times out of five when trying to connect with the VPN client on Vista Business I get a message that the Virtual adapter cannot be enabled.

Reason 442: Failed to enable Virtual Adapter

I've installed version 4.8.02.0010 of the VPN client onto a Dell Latitude D820 laptop. When I attempt to connect, I get this message. There are no firewalls running (I disabled the Windows XP firewall) and I'm running under Service Pack 2 with all of the latest security patches from Microsoft.
I even tried un-installing the client and using an older version (4.8.00.0440) and it reports a similar error in the Log file.
I'd prefer to NOT have to wipe the laptop and reinstall the O/S if I don't have to. This is the only laptop that I've experienced this problem with but it's also the first Dell Latitude D820 that I've attempted to install the client on.
Is there a problem with the Dell Latitudes and the VPN Client? Is there another way around this other than a wipe and re-install?
I've already tried replacing the profiles and still get the same problem.

Hi,
There is another thing that you can try temporarily.
Goto device manager on the computer and manually enable the virtual adapter and see if it works.
There might be some other adapters / softwares installed that you might have uninstall. Those could be some wireless adapters, personal firewall or internet security package, any other kind of adapter that you installed after installing the VPN cliemt.

VPN Client Issue after Vista Upgrade

Not sure if this should be posted here, if not please let me know.
My organization has recently implemented Vista via an Upgrade-in-Place Process that takes an imaged system (Windows XP Pro - 32bit) and upgrades the system with a network image of Windows Vista Enterprise. Applications are left installed and herein lies my problem.
I'm using Cisco VPN Client 5.0.04, the client worked fine before the upgrade, after the upgrade, not so well.
While troubleshooting I noted the Cisco Systems VPN Adapter was no longer listed as being installed under Network Adapters in the Windows Device Manager, there was however an adapter, labled 6to4 adapter with an exclamation point. I went through the uninstall process for the Cisco VPN Client, rebooted and reinstalled. When trying to connect, I can use one of two pcf files (both are a back up of one another), the first connection profile goes through the motion of connection, tries to contact the security gateway, and states "Not Connected"
I enabled logging on the connection and tried again. Here's an excerpt from that log:

Has anyone seen this behavior after an upgrade from XP to Vista? I'm I going to have to start with a fresh install? I appreciate any suggestions or advice.
Thanks,
Jimi

I finally figured out this problem and I feel it should at least be shared for another person who runs into this problem.
The problem was resolved by loading my personal certificates (the one that is read by the smart card reader and used to authenticate me on VPN) needed to be added to the personal certificates folder in the Local Machine layer.
I did this by opening up an MMC window --> Adding the certificates snap-in (in windows 7 it distinguishes 3 different layers, so choose the local user and the computer layer) --> and then copying the certificates in the personal folder located under Certificates - Current User into the personal folder located in Local Machine.
The most likely reason this happened to me is that the image I was working with had security settings blocking the certificates to be read at the current user level and not at the local machine level. Therefore, it's a problem with out image and the security policies put in place at the registry level and/or group policies placed in Active Directory. This is more of a workaround than an actual fix to the problem, but at least it pinpoints where the break is happening.
Now I can push the image back to the developers to review the security policies placed in the image.

Hello Paul,
This seems to be a known issue:
Client cvpnd.exe errors on bootup if certain vendor's firewall installed.
However, just to try further options, what if you try this?
Restart VPN Client Service if You Install VPN Client before Zone Alarm
Also check: Check Point Integrity Firewall Incompatibility, found in the link above.
From the Zone Alarm FW, make sure you have the following advanced firewall options enabled:
Allow VPN protocols
Allow uncommon protocols at high security
Enable IPv6 networking

WRT54GS VPN Connection Issues: Error code 87

Hello experts,
I have unsuccessfully tried to help my wife connect her XP laptop to her work VPN over our home wi-fi network. I have a WRT54GS v.4 router with the latest firmware, WPA2 encryption. It connects to the VPN just fine but is unable to ping any internal IP addresses and I get the following log message everytime.
1 09:58:43.546 10/10/09 Sev=Warning/2 CVPND/0xE3400013
AddRoute failed to add a route: code 87
Destination 192.168.1.255
Netmask 255.255.255.255
Gateway 192.168.1.1
Interface 192.168.1.237
2 09:58:43.546 10/10/09 Sev=Warning/2 CM/0xA3100024
Unable to add route. Network: c0a801ff, Netmask: ffffffff, Interface: c0a801ed, Gateway: c0a80101.
I have tried the following troubleshooting tasks:
a) Plugged her laptop directly to the cable modem >> Works like a charm which makes me think it has got to be a router issue.
b) Reset to factory defaults, tried running it without any encryption, tried running it in DMZ mode >> No joy, still get the same above error message in the VPN log.
c) Opened up ports 500 and 1723 for TCP/IP and UDP with her laptop's IP address >> Still no luck.
All passthrough options are enabled for VPN in the router's config interface. I have also tried disabling the router's firewall.
I am at my wit's end here guys. Is it possible that the WRT54GS isn't VPN friendly (although it seems very unlikely) and I just have to get another router? Any help is appreciated.
Edit: The VPN server is IPSec/UDP
Message Edited by sidewinder_us on 10-10-2009 07:36 AM

No, I wasn't trying to ping my router from the VPN connection, I was trying to ping the VPN host server at the office for troubleshooting purposes and the request times out everytime. I am still getting the error message in the log "AddRoute failed to add a route: code 87". I disabled "Block Anonymous Internet Requests" like you said but it didn't make any difference. I am able to ping the computer's IP address assigned by the VPN but I can't ping the host server or anything else.
It's basically connecting to the VPN but not connecting as in I can't do anything on the VPN like access local folders or run a specific software called eClinicalWorks which works fine from the office.
If I plug the laptop directly to the cable modem, I don't get that error message in the VPN client's log anymore and everything works fine.

Hi Sanjib,
Cisco VPN clinet is not supported for the windows version 8.1. And also it is EOL announced. Might be the below mentioned work around might help you. Try this.

IPhone VPN client issues

1. Even if you key in a password for the VPN client, putting the phone to sleep will cause the password to be cleared, requiring you to retype it the next time you start the client.
2. the only place to type alphanumerics in for the password is on the VPN setup screen, if you just slide the VPN switch to On, you are presented with a numbers only dial pad
3. The PPTP VPN client only recognizes maximum security, setting to either automatic or none will just hop back to maximum on save.
4. The network stack doesn't allow you to easily set up special DNS servers for the VPN connection (the equivalent under OS X is to go into System Preferences, Network and select the VPN (PPTP) adapter and enter the DNS information there.
Since we use VPN to secure our wireless network, that means our iPhone users are unable to use WiFi at the office.

Scott,
You're correct (mostly). I've experienced the same issues and have tried to work around them as follows:
1) Use a numeric password for the VPN user account. Of course, you'll have to enter it each time (did they even test this?) but at least it works.
4) Depending on your VPN device you should be able to set the DNS addresses via that. I'm using a Cisco ASA and set the DNS via the Group Policy for the DefaultRAGroup.
The bottom line? iPhone and VPN are not friends. Moreover, the iPhone has no EAP support wireless authentication. I'm a huge Apple fan but that is just stupid.

Windows 8 Cisco VPN Client Issue

I connect to several of my customers with the Cisco VPN Client Version 5.0.07.0290 and all has been working fine. In the last week, virtually every Windows 8 machine has stopped working. The client connects fine, shows it's connected, but if I go to Status -> Statistics it just shows 0 in the Bytes Received and Sent. The Bypassed and Discarded increases, but I am unable to reach any system. Does anyone know what causes this or how to resolve it? This is a HUGE problem for me as all of the work we do for our customers is via their VPNs. Every non-Windows 8 PC still works fine. And these Windows 8 PCs have been working fine until just the last week. Browsing through, I've seen posts with this same issue, but none related to Windows 8 recently. They are all Windows 7, and my Windows 7 machines are working flawlessly.
Someone help!
Thanks,
Brian

VPN Client - Pings of 1500 bytes fail?

I have a VPN client setup into a 1700 router. My customer is complaining that they can ping devices on the office LAN however, as they increase the ping size it starts to fail.
Any thoughts?

Andrew
For TCP based traffic I have found a very effective solution with the ip tcp adjust-mss command which is configured on the LAN interface(s) of the router. This command will cause the end stations to negotiate a mss that is small enough that fragmentation will not be needed. It may take some experimentation to find the optimum value to set to eliminate fragmentation. (The amound of overhead will vary depending on some options within IPSec and whether you are doing GRE with IPSec or IPSec without GRE. I frequently use 1375 in environments using both GRE and IPSec and find that works for us.)
For non-TCP traffic I have seen a solution which uses a route map to identify the IPSec traffic and to turn off the DF bit. This allows the packet to be fragmented as it passes through the IPSec tunnel. I have not used this solution so I can not speak to details of how it works.
