Create a new login in linked server

Question

Hello,
I have 2 SQL servers that are linked. I can use this query to select some values from remote DB:
exec sp_addlinkedserver
@server=N'WinServer',
@srvproduct=N'',
@provider=N'SQLNCLI',
@datasrc=N'10.3.0.217';
GO
exec sp_addlinkedsrvlogin
@rmtsrvname='WinServer',
@useself='false',
@locallogin=NULL,
@rmtuser='sa',
@rmtpassword='123456';
GO
exec sp_testlinkedserver N'WinServer';
select * from [WinServer].[MyDB].[dbo].[MyTable];
But I want to create a new login on remote computer as below but it doesn't work:
exec sp_testlinkedserver N'WinServer';
-- use [WinServer].[MyDB].[dbo].[master];
exec sp_grantlogin 'INTERNET\Domain Admins'
How can I change authentication (add user) remotely without using "sqlcmd -S ... -U ... -P ... -q ...". Because my DB users will use this link object but they will not have  sa's password of remote computer.
Thanks.

Typo: Not AS, it should be AT
EXEC ('CREATE LOGIN [INTERNET\Domain Admins]') AT Link
