Cisco Vpn Client 64 Bit Windows 10

Background

Citrix Deterministic Network Enhancer (DNE) is not a virus or a rootkit (although some anti-rootkit products may mistakenly flag it).

Citrix supplies software to a number of software and hardware companies. When they install their products on your systems, they will often contain DNE. DNE extends operating systems and network protocol devices and stacks to introduce measurement and controls. Our customers use these extensions to build products that do things like intrusion detection, VPNs, Network Address Translation (NAT), traffic measurement, response time measurement, bandwidth control, compression, content filtering, content protection, policy management, proxies, billing, packet marking, routing, protocol translation, wireless communication, secure tunnels and much more.

Citrix DNE Installation Issues

We have recently seen new or upgraded Windows 7 systems which are having problems installing DNE. In many of these cases, a registry value that determines the number of drivers that can capture packets is too low. If you think you are having this issue, try the following:

• Using regedit.exe, look at HKEY_LOCAL_MACHINESystemCurrentControlSetControlNetworkMaxNumFilters.
• If the value is 8, please set it to 14, reboot, and then retry the installation.

More often we see other problems that arise installing DNE. Usually these are the result of corruptions in the operating system (a known Microsoft bug), back level device drivers, incompatible 3rd party software or overzealous firewall or antivirus programs.

We have seen issues with Dell Security Device Driver Pack, with Trend Micro and with McAfee Antivirus packages when they are configured to scan the kernel and drivers, and with Symantec Endpoint Protection which seems to aggravate the Microsoft bug where the OS cannot install or uninstall DNE or other IM drivers like DNE. If it’s possible your problem is caused by a firewall or antivirus program, be sure to double check your firewall/antivirus settings or disconnect from the network and disable your personal firewall/antivirus program. Then try the installation again. Re-enable your firewall and antivirus programs, then reconnect to the network.

If that doesn’t work, we have a utility called Winfix that can clean up most Windows operating systems to enable installation of products that use DNE and other products like DNE.

We suggest trying to uninstall the program that uses DNE (e.g. a VPN client), then download and run the following:

1. If on an internal Citrix network, use winfix.exe
2. Download and install the latest DNE if on an internal Citrix network: dneupdate.msi for 32-bit and dneupdate64.msi for 64-bit.

Then reinstall the product that uses DNE.

If that fails, you might try downloading and running ccCleaner (a freeware program that sometimes helps), Microsoft’s MSI cleanup tool, and/or as a last resort, try a Windows Repair, and repeat the steps above. If these don’t work, then it is recommended to reinstall your operating system to resolve the corruption.

Citrix DNE Upgrade

DNE now supports WWAN devices in Win7. Before downloading the latest version of DNEUpdate from the links below, be sure you have the latest drivers for your network adapters by downloading them from the vendors’ websites.

If on an internal Citrix network, use dneupdate.msi for 32-bit and dneupdate64.msi for 64-bit.

Citrix DNE Downgrade

If for some reason you need to downgrade DNE from the current version, follow these steps:

1. Uninstall DNEUpdate
2. Uninstall any products that use DNE
3. Reboot
4. Install the older DNEUpdate from the links below and then reinstall the program(s) that use DNE.

Other Citrix DNE Issues

Crashes - BSODs

With tens of millions of copies of DNE installed and over 12 years in the market, there are no known crash issues with DNE. However, because DNE is a kernel-level NDIS module that relies on packets from other drivers, we sometimes see crashes that appear to be in DNE. Generally these are caused by bugs in other products or drivers.

Security Warnings

A minor security problem has been reported for early versions of DNE. Refer to the Citrix Security Bulletin Privilege Escalation Vulnerability in Citrix Deterministic Network Enhancer (dne2000.sys) for more details.

From a users perspective it’s almost just a different way to do the same thing. The major differences to a company considering the move to AnyConnect would be:

1. The licensing fees. The security IOS that runs on routers we sell customers generally includes IPSec VPN clients. The AnyConnect has separate licensing fees through Cisco. Some equipment includes licenses, others do not (it’s hardware specific). So there is usually an additional cost associated with the AnyConnect VPN Client.
2. AnyConnect runs on port 443 so many firewalls will not interfere with traffic on AnyConect vs an IPSEC software VPN. Often users firewalls will block IPSEC traffic or interfere with it (home users firewalls, Barnes and Nobles, Cell card firewalls, etc)
3. The AnyConnect can be launched from a web page on the router. This allows for ease of deployment.
4. AnyConnect reportedly uses more processing power and systems resources to establish the connection. This is usually no big deal because you are actually using it on a quicker, newer machine running a 64 Bit OS.
5. Ease of administration (this could go either way). Sometimes Eclipse WAN support has had calls around a corrupt install of the VPN client. We haven’t really had any client troubles yet with AnyConnect although it’s fairly new.
6. The Install package is a lot smaller for AnyConnect.
7. There is support for different Operating Systems using the Cisco AnyConnect please see http://www.cisco.com/en/US/prod/collateral/vpndevc/ps6032/ps6094/ps6120/data_sheet_c78-527494.html
8. According to Cisco’s documentation they state “Only 32-bit Windows support is available in the Cisco VPN Client. For 64-bit (x64) Windows support, customers must upgrade to the next-generation Cisco AnyConnect VPN Client.” Cisco has recently deployed a beta version of the 64 bit IPSEC client for Windows 7 users. Whether or not they will support it in the future remains to be seen.
