@atripp Thank you! I was able to fix that issue. After changing the service to "Local system account" I gave full permission of Buildmaster database for the user "NT AUTHORITY\SYSTEM"

Hi @atripp,
Thank you so much for your answer. Actually, I am trying to stop the IIS Pool (that is connected to only 1 site) without stopping IIS pool I can't deploy artifact files.
I tried to change the BuildMaster Service and BuildMaster Web Server to run under Local System Account but after restart service BuildMaster web app not running so I have to revert it back.

Any suggestion?

Thank you!

Its .NET app and build are working fine but when I tried to deploy it on IIS I got this error.
I have given full permission to the site folder as well but still the same error. I am using Windows Server 2019 Standard.
I tried to use IIS::Stop-Site Script as well but same error there as well.
