Thanks for your attempts to help. I "solved" the problem by creating a new user ID and giving it the access rights I was trying to give my primary Windows login ID.

Using Visual Web Developer Express and SQL Server 2005 on an XP development machine. Was using development server in VWDE to view pages, using following connection string: |connectionStrings| |add name="RHConnectionString" connectionString="server=MIKE;database=Rotary;Trusted_Connection=True;"/| |remove name="LocalSqlServer"/| |/connectionStrings| Needed to test with SSL. Installed SSL certificate (using your makecert procedure, thanks). Moved web site to IIS and opened in VWDE. Development connection to database works, but pages get Login failed for user 'MIKE\IUSR_MIKE'. SQL Server configured for Remote Connections and mixed Windows Authentication and SQL Server authentication. Any help?
