Thank you !

Thank you for your response, but the problem is not solved.

LogonId is necessary because ORIGINAL_LOGIN() is insufficient (for example: two windows user name equal in contemporary Terminal Server sessions).

Sysprocesses table...

Thank you for response.

I tried with ORIGINAL_LOGIN() and SUSER_ID() but not return the value specified number of LogonId.

Thank you for your response.

I do not use xp_cmdshell to not affect the security of SQL.

I will try SQLCLR.
