>I installed MS W2K Server on an IBM 205x Series with 2.4 GHz speed and
7600MB memory about two months ago. This server keeps hanging at least once
a week. When I check on running processes on Windows Task Manager screen, I
observe the following: DLLHOST.EXE process appear many times and one of
this process always has CPU 99 for all the hours the server has hanged e.g.
56:02:23hrs.
When you reboot, it normalises and hangs again after a few days. What is
the use of DLLHOST.EXE process and why does it engage the processor fully
making the machine hang. What can I do? Please help.

------------------------
DLLHOST.EXE is a surrogate process provided by Windows. It is provided so
that a COM+ .dll file can run in it's own process space. If you are
familiar with COM+ (the concept of having an application composed of an
exe and multiple .dll's), you will know that you cannot have a .dll in
it's own process, it must be loaded under an .exe. If an application is
written such that it requires a called .dll to run in it's own process,
then DLLHOST.EXE will be launched as the .exe for a COM+ .dll
There are a number of issues with COM+, including memory leak issues, that
have been fixed in KB article 822618: "INFO: Availability of Windows 2000
Post-Service Pack 4 COM+ Hotfix ".
Installing this hotfix should be your first troubleshootings step.
The next step, would be to find out what .dll is running in DLLHOST.EXE
that is causing the problem.
