Hi everybody, I installed the SP1 on a SQL Server Enterprise Edition and, as
a consequence, couldn't start the SSIS service no more.
So I tried to install the Hotfix for the SP1 in order to solve the problem.

But, since I had made the mount of a volume in the "Data" directory in
"Microsoft SQL Server\MSSQL.1\MSSQL" (in order to expand the space
available), I could not install the Hotfix because it provokes the loss of
the mounted volume and, further, it signalled an error.

Any hints on how to solve the problem?

Thank you very much.
