Username disappears

Hi All,
I am running TOMCAT 8.5.15 on a Windows 7 server with SP1. Although it is
not consistent, the password value for the specific username used to run the
TOMCAT service disappears when the service is stop and started again. The
starting of the service fails because the value of the password disappears.
Once the password value is re-entered with the password value, the TOMCAT
service starts without any issues, has anyone encountered this issue?
I look forward to your response.
Hi.
I have never seen the behaviour which you describe above, although I regularly
run Tomcat as a Service on Windows systems, in multiple customer networks.
First, maybe something which you should read :
https://wiki.apache.org/tomcat/FAQ/Windows#Q11
In a way, this explains why the Tomcat code itself is very unlikely to contain anything
which would modify this Windows user's password. (If anything, it would be the
"wrapper"
program described in that article.)
My guess would be at this point : if the user-id in question is a Windows
Domain user-id, then mybe some Windows network policy is the cause of this
password reset.
Ask your Windows network sysadmins.
Hope this helps.

Hi Andre,
Thank you for your response and feedback. I had reached out to our windows
support group only to be told that it must be caused by the third party product.
What's worse is that all installations of TOMCAT (Stage and Production)
encounter the same behavior when the service itself it stopped.
I was reaching out to the TOMCAT user community in the event that there might
be a permission that needs to be granted to a file in which the service account
Username and password might need to be entered.
So I am once again at square one, however, I will follow your suggestion and
reach out to the networking group to see if they can shed light on this
situation.
Thank you.

Another suggestion : if you have read the article to which I pointed you, you will see
that the "wrapper" program which actually runs the JVM which runs Tomcat, actually stores
its parameters in the Windows Registry.
It is the same for the userid/password which you enter in the service
description.
So maybe it is not an issue linked to Tomcat per se, but instead due to the fact that by
entering this password, you are modifying the Registry.
And perhaps there is some network script which regularly removes such changes, when made
by a user who does not have the correct permissions to do so ?
It may thus be that it is not the Tomcat start/stop per se which resets this password, but
that this happens asynchronously, and that you just notice it when you are trying to
restart Tomcat.
You could try the following experiment :
- set the password for that user, start Tomcat as usual, and leave it running
- then, after a suitable pause, try to login to that same workstation, as this Tomcat
user, using the same password which you set.
If it does not work, then you know that it has nothing to do with stopping
Tomcat.
