Fix: No Mapping Between Account Names and Security ID was Done
What is the problem?
The problem is that when you try to connect to a remote computer using a different account name than what is used on the local computer, the security ID (SID) cannot be mapped correctly and you get the error “No mapping between account names and security IDs was done”.
To fix this problem, you need to use a tool such as PsExec to connect to the remote computer using the correct account name.
How to fix it
When you see the “No mapping between account names and security IDs was done” error, it means that the computer could not find a specific user account in its security database. In order to fix this, you need to find the account in question and either delete it or change its name.
To do this, open the Registry Editor (regedit.exe) and go to the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
In this location, you will see a list of all the user accounts on the computer. Each account will have a unique number as its name. Find the account that is causing the error and delete it.
If you are not sure which account is causing the error, you can try changing the name of each account to something unique (e.g. “Account1”, “Account2”, etc.) and then restarting the computer. The account that causes the error will have the original name.

When you see the error message “No mapping between account names and security IDs was done,” it means that the Security Accounts Manager (SAM) could not resolve a specific account name to its security identifier (SID). This can be caused by a number of factors, including incorrect permissions, issues with the user’s profile, or problems with the SAM database.
In order to fix this issue, you will need to determine what is causing the problem. One way to do this is to check the Event Viewer for any error messages that might give you a clue as to what is going on. You can also try resetting the user’s profile or recreating the SAM database. If all else fails, you may need to contact Microsoft support for further assistance.
