The SQL Server service pack Setup program may fail if the 'probe' user has been removed from the master database or if the 'probe' login does not exist. The failure message is:

Setup initialization could not be successfully completed.
ISQL.EXE could not be executed. Please check the relevant .OUT file.

In the Instrepl.out file, you will find the following output:

   Adding logins and users for replication.

   Msg 4604, Level 16, State 1, Server XYZ, Line 1
   There is no such user probe.


The Instrepl.sql script attempts to grant permissions to execute a replication stored procedure. If the probe user does not exist, this GRANT fails, causing the service pack Setup to fail as well.


To work around this problem, add the probe login and user to the master database, using the following process:

   use master
   exec sp_addlogin probe, NULL, master
   exec sp_adduser probe

From ISQL/w, open the Procsyst.sql script in the Mssql\Install directory and run this stored procedure. This will grant other permissions to the probe that are necessary for using Performance Monitor.
