Hello, my configuration is as follows:
- Windows 2000 Server SP2.
- Microsoft Exchange 2000 SP2.
My problem is that SMTP service (inetinfo process) consumes all the
CPU just after starting. Besides, if I try to stop SMTP service,
Windows timer finishes and the service if not stopped (it remains in
"Stopping" status). I can only stop inetinfo process using kill.exe
program, but all IIS services are restarted immediately and the
problem continues (likely, some program needs these services running
and restarts them).
I have applied last Microsoft patches for Windows 2000 and rebooted
the machine several times, but the inetinfo process always takes
possesion of the whole CPU. I know that SMTP service is responsible
because I disabled it and CPU occupation was reduced even with
inetinfo process running.
Of course, I applied patches Q313450 for SMTP and Q320436 for
Exchange, which talk about malformed SMTP commands that can cause
denial-of-service, but the problem remains. Well, I have observed in
Windows Registry that, strangely, there is no "Filelist" key under
\\HKLM\\Software\Microsoft\Updates\Windows 2000\SP3\Q313450 (all SP3
patches have and this is mentioned in Microsoft documentation about
patch Q313450). I have re-installed the patch several times, but no
changes are made to the Registry.
I'm thinking about uninstalling IIS, but I dont know if this can be
harmful for Exchange (I think so).
Could you let me a hand?
Thank you very much.
