Unable to determine domain for account Uninstall ecc6 on domain

Hello All,

I am trying to uninstall sap ecc6 from a server on a domain . While proceeding with uninstallation, it got stuck with following error details after entering the database details on sapinst.exe

####

FSL-01018 Unable to determine domain for account S-1-5-21-705529515-409054649-1020538192-1108. The group name could not be found.

ERROR 2008-01-02 10:29:35

MUT-03025 Caught ESyException in Modulecall: ESAPinstException: error text undefined.

I am trying to uninstall by logging to that server as administrator of domain . Can you guys give me some clue to fix this.

Thank you in advance
