Sorry to tell but...
On a windows 7 home machine, with a HOSTNAME in the stunnel conf, NO
DELAY at service startup :
I can start the service, then reboot,
then, at first, my log file is saying ": Error resolving 'HOSTNAME ':
Neither nodename nor servname known (EAI_NONAME)"
and later, when I try to use the tunnel (and at that time dns is
working), resolving is working...
and everything is OK so....
Even if dns is NOT available at startup, stunnel 504 is able to resolve
"later" the remote server hostname.

So I am sorry to say that I cannot reproduce that bug.
Anyway there are many services, on a heavy loaded machine, that can slow
down the service startup or interfere with file management :
Antivirus ? try to deactivate it.
Firewall : the same...
any other piece of software that is not absolutely necessary at boot time.
Plus : Even if you don't use hostnames in conf file I suggest that you
try "dnscache" dependency anyway:
because you probably have hostnames in your certificates.

Delay: Yes, Automitic (Delayed Start) works like a charm.
Capi engine: Yes tried turning it off
32 bit or 64 bit: 32bit running on 64 bit server. I don't see a 64 bit

dnscache: Haven't tried it yet.
- stunnel works fine on the server specifically with the service set
to Automatic (Delayed Start). And I even tunnel properly to other
machines so it not firewalls or routers or network.
- Only when it's NOT (Delayed Start) stunnel doe not seem to start
even though the service shows as started.
- I managed to tunnel from my Desktop to the Server. I have not tried
automatic service startup on Desktop because I don't have enough
privilidges. But trying to setup the server, since that's the machine
that will have stunnel in production.

Have you tried to change the service dependency from "TCPIP" (the
default in the code), to "dnscache" (ok, EVEN if you do not use
hostname resolution),
this is just to be sure that stunnel relies on something that is
using tcpip as well.
question : what kind of network interface do you have :
wifi ?
ethernet board ?
Are you traversing multiple routers ?
Are you using multiple firewalls ?
Have you tuned a delay as suggested a few days ago ?
Can you try without specifying "capi engine" ?
Are you using stunnel 32 bits or 64 bits : if 64, try the 32
version as well.
I am reviewing the code and soon enter some test on w7-32bits.

When you observe that log is empty and that "stunnel shows as

do a CTRL ALT DEL to check if there is any process called

I have a doubt that, although scm says stunnel is running, in
fact it is not.

Hi I used administrator account and defaults to install. It

The service is set to run as local system account and

Once the machine is booted... Login open service control

And it comes up properly.
My config is as follows:

Hello,
I can tell my patch was adressing read file error on
conf file,
but, unfortunately, not at all "dependencies of stunnel
service at start up",
which is likely to be the core pb preventing stunnel to
start correctly at boot time for people on that thread.
Michal added explicit dependencies at startup, that is
necessary to solve that bug. I did not check yet its
implementation.
But maybe some services, although started, are still
"not ready" when stunnel starts, so that this makes
stunnel fail.
I suggest that stunnel checks, not only the
availability, but also the "efficiency" of the DNS
service by trying to resolve a well known server.
it should retry during, eg, 3 seconds, and then stops
with some reports if failing to resolve the hostname,
either by lack of network, or by lack of answer from the
name resolver.
But...it seems that when having problems at startup, it
cannot even log anything....maybe this is due to the
identity of "system user" of stunnel at that particular
moment: user that may have no right to write on the HD.
People should check also the installation location of
stunnel : it is supposed (and have predefined shortcuts
for that) to be installed PREFERABLY in "c:\program
files\stunnel".
I recommend to use that location.
They also should try to resolve by hand the hostnames
they put in their stunnel conf file, just to be sure.
On some network or machines, maybe there is a problem
with the firewall and SOME services tunneled by stunnel
on forbidden ports.
On another hand, it sounds strange that just restarting
stunnel (in user mode or service mode ?) is solving the
problem :
this sounds like unavailability of DNS at startup.
I did not investigate that particular problem, but I
will perform some tests soon with the last 504 (or 505).
Yours sincerely

Using Stunnel on several Windows Server 2008 R2 SP1
machines (all such machines are X64 as the OS is only
released as X64).
During August of 2014 I reported in this forum the
current version of Stunnel would not function as a
service under the above OS, even if using a delayed
start, it might run but it would not work. I reverted
to using version 4.35, which did work properly.
Pierre DeLagge was kind enough to provide me with a
copy of his patched Stunnel 5.02, which I am still
using and which is working flawlessly on my production
servers. No delayed start required.
I am wondering if Pierre's 5.02 patch has been
incorporated into the most recently released Stunnel,
5.04? Has anyone been successful in getting the most
current version to actually work under the above
environment without delaying the start of the service?
Just to add a little color and background to the story,
I am using the native WS2008R2SP1 SMTP server on each
machine, in conjunction with Stunnel, so as to forward
OS event notifications through a gmail account.

Same issue. Service shows as started, but no log. If I
go manual restart it works.
Have to put delayed startup.

Thank you for testing it.
