154 MetaFrame Solutions Guide

Limiting the Impact of Memory Leaks

While there is no way to prevent memory leaks, rebooting the MetaFrame server

whenever possible can prevent memory leaks from compounding. Rebooting the

server has the added advantage of preventing system degradation caused by

disconnected user sessions, crashed applications, and runaway processes. A

regular reboot can be scheduled using the Tsshutdn command at the command

prompt. For more information about the Tsshutdn command, type tsshutdn /? at

a command prompt.

Resolving Driver Conflicts

I just installed the Canon GP200F printer/fax drivers on my MetaFrame server.

Now, every time I run Word 97 and select the Canon GP200F to print to from an

ICA Client, I get an error on the MetaFrame server.

The driver Dlls are disrupting the load process by, perhaps, having conflicting

base addresses that cannot be rebased. It could also be that the Dll initializations

fail because too many implicitly loaded Dlls need thread local storage.

One way to find out is to get the Listdlls executable from www.sysinternals.com

and run it in a command window as follows: Listdlls. You can also run Listdlls

/help for additional command line options. This lists all the Dlls in the address

space and where they are loaded.

Setting up a MetaFrame Server Kernel Debug Session

Kernel debugging is a process that uses the built-in debugging features of

Windows 2000 with Terminal Services installed to gather information for

detecting, isolating, and resolving system problems.

Kernel debugging involves two computers:

K The computer being debugged, referred to as the target computer

K A second computer that controls the execution of the target computer, called

the host computer

The host computer runs an application called the kernel debugger that is used to

examine memory and processor status, single-step through programs, and perform

other operations useful in problem determination. The target computer can be

allowed to run until an error condition occurs or it can be stopped at any time. For

Intel-based systems, the kernel debugger application is I386kd.exe.

To allow symbolic debugging (that is, debugging using descriptive names instead

of numbers), symbols are loaded onto both target and host computers. These

symbols contain information used to present data to technical personnel in a more
