internal users are using browser in our intranet and after awhile the
process named lexbcs takes 100% of the CPU resources and locks
everyone up.  Browser start page used then is not accessible and all
users are locked. I then reboot system.  This is a major problem
during a normal workday.

The service is named   lexbces    I originally stated   lexbcs.

Greetings!

The problem is caused by a piece of software from LexMark, a printer
company.

I simply cannot state this any better than this:
http://www.answersthatwork.com/Tasklist_pages/tasklist_l.htm

"This program is a component of the Lexmark MarkVision software.  If
your Lexmark printer comes with an internal network card, you will
need to install MarkVision to configure that network card.  This
results in LEXBCES running as a background process on Windows 9x and
as a service in Windows NT4."


"Recommendation : 
If you are not experiencing any problems, leave alone.  In our case,
however, we have found the MarkVision software extremely buggy, to
cause Windows startup problems, to cause serious performance hogs, and
a number of other problems.  As a result, while we often recommend
Lexmark printers, particularly for the high end lasers, we now never
ever buy Lexmark printers with in-built network cards – we use
external Intel Netport Express print servers instead."

And my contribution to the answer:  Uninstall the MarkVision software.
 If you need networked pritner support, I agree with the
recommendation for the Intel network print servers.

Good luck, and if you need further information, feel free to ask for
clarification.

Search Terms:
"lexbces"

Search your system looking for the keyword "lexbcs" and possibly the
filename lexbcs.exe or lexbcs.dll.  Find the corresponding program and
rename/disable/delete it.

If this does not work, try using pstools v1.55 and handle v2.01 from
http://www.sysinternals.com to investigate the process and the files
it is using.

We have Norton anti-virus functioning. It is updated regularly.

There is also a service named Lexbces.exe that is a two way
communication protocol between the PC and the printer, this lets the
CPU know when your out of ink. This is also very buggy.

Under NT 4.0 I know you can

In the control panel disable the LEXBCES Service (you will have to
stop the spooler.)
Set Lexbces to Disabled.
run CMD >> Lexbces.exe /u 
Delete any Lexbces.exe on your drive
Run Regedit

Go to the HKLM Current Control Set, Services, Spooler, And delete the
Depend on service Dword.

Restart the PC. 

Spooler now starts without the lexbces service. Eliminating many
problems with physical memory dumps while trying to print.
