each type of file. You must use xcopy to copy the Symbols directory and all its

subdirectories to the %SystemRoot% directory on the target computer. These

symbols are also copied to a directory on the host computer; this can be any

directory and does not have to be the %SystemRoot% directory. These directory

structures are referred to as the symbol tree.

If hotfixes are installed on the MetaFrame server, the symbol files must be

installed in the proper order: first the base MetaFrame symbols, then the hotfix

symbols. This ensures that the symbols match the executable code.

Kernel Debug Configurations

There are two basic kernel debug configurations: local debug and remote debug.

A third type of debug configuration, the ICA debug, is a variation of local debug.

Each configuration is discussed below.

In a local debug configuration, the host and target computers are in close

proximity and are connected by a null-modem cable. While this is the simplest

debug configuration, it can only be used for on-site debugging.

In a remote debugging configuration, the host and target computers are connected

through dial-up modems. This configuration allows a support representative to

dial into the target computer located at a remote customer site from a host

computer located at Citrix headquarters.

In some cases, the support representative is not able to directly access the target

computer. If two MetaFrame servers are at the remote site, the support

representative can perform an ICA debug configuration.

Much like the local debug, the host and target computers are in the same location

connected by a null-modem cable. In addition, the host computer is configured to

accept an ICA dial-in connection. The remote support representative dials in to the

host computer and runs the kernel debugger in a remote session. This method

combines the simplicity and reliability of a local debug with the ability to remotely

debug a customer’s target computer.

Requirements for Debugging

To perform kernel debugging, you need the following equipment:

Target system: MetaFrame server with any hotfixes installed

Host system (local and ICA debug sessions): MetaFrame server with any

hotfixes installed
