Cannot Re-Enable DCOM...Machine Hanging

I have messed up a Windows 2003 Web Edition server by turning off DCOM.
Apparently IIS uses it heavily and after a reboot the machine is hanging and
the desktop does not draw for any user including administrator.

I disabled DCOM by using DCOMCNFG and unchecking the enable DCOM on this
computer checkbox.

I cannot reenable DCOM by the same application because upon reboot it
behaves abnormally and crashes in many places. I tried to enabled DCOM
manually changing the following registry to the value Y:

HKLM\Software\Microsoft\OLE\EnableDCOM

On reboot, the problem does not go away. Further, the DCOMCNFG application
still does not have the enabled checkbox showing as enabled, so apparently
more steps are required.

What is the most reliable way to guarantee re-initialization of the DCOM
environment?

Re: Cannot Re-Enable DCOM...Machine Hanging

Can you go into Safe Mode to do what you need?

FYI:

IIS6 on Windows Server 2003 does not use DCOM. Only if you switch it
into IIS5 Compatibility Mode since by definition that must use DCOM
for compatibility.

Also, Windows Server 2003 runs without DCOM enabled.

However, you may be running other 3rd party software on the server
with NT Services that require DCOM. These services would be running on
reboot, before and during your user login, so they may be breaking/
hanging and causing your issues.

I guess my question was what do I need to do to reinitialize DCOM. It's
not clear that safe mode helps here since it's not about stopping some rogue
service (for example). I already enabled the registry option (per my
original post) that is required to "enable" DCOM, and yet DCOMCNFG doesn't
show DCOM enabled after a reboot.

Okay, I sense an educational moment coming on. :) First it appears our
developers had inadvertently installed IIS 5 when they installed an older
Visual Interdev. At least when I start IIS admin on the affected machine
it shows version 5.0. So it looks like this is involved somehow with
this problem, although even then I am unclear on why turning off DCOM broke
the entire computer, not just IIS 5.0.


> Also, Windows Server 2003 runs without DCOM enabled.

Just to be more elaborated on this point, every Windows 2003 standard and
web edition server I have installed leaves DCOM on. I trust your point is
that it is safe to turn it off, and that makes sense, which is why the
result I got is all the more puzzling.

It really appears to involve the core desktop functionality, as the desktop
takes a very long time to draw on startup (maybe 10 minutes), and some
applications take a while to startup. Perhaps Interdev overwrote some key
functionality for the desktop?

I spoke too soon. IIS 6.0 is installed on the computer that is hanging
after DCOM was enabled. If you start IIS Admin as a non administrative
user, it (incorrectly) reports that it is running IIS 5.0. I guess that is
a bug. Running it as administrative user reports IIS 6.0.

So, since IIS 6.0 and W2K3 do not depend on DCOM, it's a mystery why
disabling DCOM and rebooting broke the computer.

Equally a mystery is why DCOM cannot now be re-enabled in a straightforward
way, by the usual registry change.

Re: Cannot Re-Enable DCOM...Machine Hanging

Will,

With IIS 6 (the only IIS one can install on W2k3) one has the
option on installing the IIS5 mgmt interface in order to manage
IIS5 elsewhere. There is also ability to run in IIS5 compatibility
mode. Make sure you are not confusion either of these.

The reg key you mention,
HKLM\Software\Microsoft\OLE\EnableDCOM
is the only thing in the reg that I am seeing altered when one
toggles that checkbox in the properties of the My Computer
node in Component services.

Have you attempted inventorying of what all else is installed
on the machine? It is quite unlikely the an Interdev install did
what you hypothesize, but then, it has been many, many years
since I had an install of Interdev around.

Re: Cannot Re-Enable DCOM...Machine Hanging

What happens if you go into SafeMode to run dcomcnfg to re-enable
DCOM.

I suspect it is some auto-start NT Service that requires DCOM and is
now "hanging" and preventing you from fixing the situation. If so, you
want to run in safe-mode to not have those extraneous services start,
so that you can re-enable DCOM without their hinderance.

Yes, Windows Server 2003 defaults with DCOM enabled, but it can be
installed with DCOM disabled, and it is also user-configurable.

What you can observe is very different from what is going on. I tend
to agree with Roger about your hypothesis.

Re: Cannot Re-Enable DCOM...Machine Hanging

I suppose it is possible that use of the dcomcnfg interface does
touch some settings other than the reg key, such as in the comadmin
catalog, so this recommendation to try safe mode is very good idea.

Will? have you discovered anything? found a way ?

Unfortunately, even in safe mode, DCOMCNFG is throwing a null pointer error
when you try to re-enable DCOM using that application (it does look like
that much is a Microsoft bug).

So guess it's time to pay a visit to Microsoft Shanghai again. We'll open
up a ticket.

Unfortunately, even in safe mode, DCOMCNFG is throwing a null pointer error
when you try to re-enable DCOM using that application (it does look like

So guess it's time to pay a visit to Microsoft Shanghai again. We'll open

It must be due to some interaction with another latch-down in
effect on the box, or a peculiarity of the web sku of Windows,
as I have toggled that many times on W2k3 servers without
running into what you have happening.
