Help!! Apache2 service specific error 1

[pocean]

I have installed XAMPP everything went fine. Apache was installed successfully and was running.

Then I stopped Apache and I could not get it back to work.


I started the Apache batchfile and I got this message:

Apache2: Service is already installed.
Now we Start Apache 2
The Apache 2 service is starting..
The Apache 2 service could not be started.
A service specific error occured: 1.
More help is available by typing NET HELPMSG 3547


Also, if I go to XAMPP, to port checking, I see that the ports that should be used by Apache 2 are free


I am very new in all of this. Could somebody tell me in detail
what is error 1 and what I am supposed to do?

Thanks pocean

I started the Apache batchfile and I got this message:
Apache2: Service is already installed.

That's the batchfile for installing Apache as service.

If you want start Apache, use "apache_start.bat".

Thanks! I found the cause of the problem. There was an error on apache\confg\httpd.conf related to the ServerName.
I fixed the problem and Apache is running

But, then I got a message from Windows Security Alert telling me that Windows firewall is blocking Mercury.
The program is asking if it should keep blocking Mercury/32 Core or not.

What should I do. Should I keep Mercury blocked or not?
Thanks

Did you need Mercury?

[pocean]

Yes, I do.

So, I guess your answer will be. Unblock it

Right?

Yes, I do.

So, I guess your answer will be. Unblock it

Right?

If you need webmail, then unblock it. if not, you can leave it be.
