How to recreate system users in Plesk for Windows Server

Connect to the server via RDP.

Open Local Users and Groups snap-in by executing the following command in command prompt:

C:\> lusrmgr.msc

In case the server is a domain controller, Active Directory Users and Computers should be opened instead:

C:\> dsa.msc

Re-create Plesk Administrator user. It must be a member of Administrators group.

Starting from Plesk Onyx, it can be done with the command below:

C:\> plesk sbin usermng.exe --install-plesk-admin

Re-create Parallels Panel users group.

Run Plesk Reconfigurator > Repair Plesk installation tool and check options Plesk Server Accounts, Plesk Services.

In Local Users and Groups (or Active Directory Users and Computers) snap-in create IUSRPLESK_sqladmin user and repair MSSQL Webadmin:

C:\> "%plesk_cli%/repair" --reconfigure-mssql-webadmin-site
C:\> "%plesk_cli%/repair" --update-mssql-users-permissions

Re-create Plesk system users as follows:

C:\> "%plesk_cli%/repair" --repair-all-webspaces-system-users
C:\> "%plesk_cli%/repair" --regenerate-web-server-users-password
C:\> "%plesk_bin%\dbclient.exe" --direct-sql --sql="SELECT displayName FROM domains" > domains.txt
C:\> for /f "skip=1" %i in (domains.txt) do "%plesk_dir%\bin\repair.exe" --reconfigure-web-site -web-site-name %i
C:\> "%plesk_dir%\bin\repair.exe" --synchronize-protected-directories-storage
C:\> "%plesk_dir%\bin\repair.exe" --repair-all-webspaces-security
C:\> "%plesk_dir%\bin\repair.exe" --synchronize-impersonation-storage
C:\> "%plesk_dir%\bin\repair.exe" --synchronize-protected-directories-storage
C:\> for /f "skip=1" %i in (domains.txt) do "%plesk_dir%\bin\repair.exe" --repair-webspace-security -webspace-name %i

Re-create FTP users as follows:

C:\> "%plesk_dir%\bin\repair.exe" --reconfigure-ftp-sites

execution can fail with the following error:

CONFIG_TEXT: C:\Program Files (x86)\Plesk\MySQL\bin>"%plesk_dir%\bin\repair.exe" --reconfigure-ftp-sites
ftpmng failed: No mapping between account names and security IDs was done. (Error code 1332) at LookupAccountName

(Error code 1)

In that case, create group specified in the error in Start > Computer Management > System Tools > Local Users and Groups > Users (or Active Directory Users and Computers), e.g. MSFTP7_027875036 in that example and re-run repair tool once again.

If Plesk FileSharing feature is installed, check that IWAM_FILESHARING user exists in Start > Computer Management > System Tools > Local Users and Groups > Users (or Active Directory Users and Computers) and create it if not.
Go to Home > Tools & Settings > File Sharing Settings and specify Username for file access and Password for file access, then click OK. Create a user via Start > Computer Management > System Tools > Local Users and Groups > Users (or Active Directory Users and Computers) if such user is missing.

If webmail is being used, check that related IIS user exists and create it if not:

CONFIG_TEXT: IUSRPLESK_atmail - for ATMail
IUSRPLESK_horde - for Horde
IUSRPLESK_smwebmail - for SmarterMail

Recreate MailEnable users IME_ADMIN and IME_USER:

1. Start the MailEnable Installer:

   C:\> "%plesk_dir%\Mail Servers\Mail Enable\Bin\MEInstaller.exe"

   OR

   C:\> "C:\Program Files (x86)\Mail Enable\Bin\MEInstaller.exe"

2. Select the second entry (Web application reconfigure)

3. Enter the new password for system users and click on Ok

4. Select (MailEnable WebMail) MailEnable Webmail IIS binding for webmail and click Next

5. Uncheck Configure web admin as an IIS Virtual Directory and click on Next
