Named Instances and SS2KI saw Alex's post on installing a named instance of SS2K5 and having
issues with SS2K. I wanted to note that Dale Corey and I are working on
a SQL Server Management Studio book and I needed to check some things
using the RTM code. I need my desktop to work, it's the primary place
where SQLServerCentral.com runs from, so I took the laptop and
installed the RTM developer edition code. Now I already have SS2K on
there and wanted to keep it, so I added an SS2K5 named instance to it.
No issues. Both start fine for me. XP, SP2.
Not sure what happened with Alex, but it worked for me. I have had the
June and Sept CTPs on here prior to this, same named instance name.
