Citrix Gateway, formerly Citrix NetScaler Unified Gateway

Citrix Virtual Apps, formerly XenApp, fits the enterprise need to bring legacy apps into a cloud management environment.

This article describes how to fix Citrix DNE installation and other issues.

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_MACHINE\System\CurrentControlSet\Control\Network\MaxNumFilters.
• 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.

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.

If on an internal Citrix network, use
dneupdate_3_22_8.msi for 32bit and
dneupdate64_3_22_8.msi for 64-bit.

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.
