[FIXED] Jenkins sever startup issue

Issue

I have Jenkins server installed on a dedicated Jenkins machine(Windows 10). I was trying out something and in services, I have changed the "Logon As" from local System to my credentials. Since then I am unable to access Jenkins server, it shows the page with the content mentioned below

Skip to content [Jenkins]Jenkins [Jenkins]Jenkins

When i click on skip to content it shows the below error

java.io.IOException: Access is denied

I also changed the "Logon As" in services to the one that was previously present i.e. "Local system". The issue still persists. After changing it to local system, when i manually start the service it automatically stops after few seconds.

Any help to retrieve the server back will be appreciated.

Thanks in advance Sharan

Solution

I found the solution:

After changing the "Logon As" in services to the one that was previously present i.e. "Local system" from my credentials, I restarted the system. I am now able to access the Jenkins server.
