I am getting this same error, when running Jupyter Notebook as a service using nssm as per these instructions.

pywintypes.error: (1332, 'LookupAccountName', 'No mapping between account names and security IDs was done.')

I'm running the latest component versions, I think:

Package            Version
------------------ -------
jupyter            1.0.0
jupyter-client     6.1.2
jupyter-console    6.1.0
jupyter-core       4.6.3
notebook           6.0.3
pywin32            227
pywinpty           0.5.7
...other packages not listed

Hello Everyone,

If anyone still having this issue especially when using NSSM software on Windows 10 or Windows Server 2019. I have fixed it by manually applying the fix jupyter/jupyter_client#478. One more important if you still face same issue even after applying the above fix then do follow i.e.

1. Manually verify Lib\site-packages\jupyter_client\connect.py file contains following lines i.e.

admins = win32security.CreateWellKnownSid(win32security.WinBuiltinAdministratorsSid)
user, _domain, _type = win32security.LookupAccountName("", win32api.GetUserName())

2. Manually verify Lib\site-packages\jupyter_core\paths.py file contains following lines i.e.

user, _domain, _type = win32security.LookupAccountName("", win32api.GetUserName())

This will fix the issue.

Thanks & Regards,
Asma Khalid
