Hi,

I have installed Visual Studio 2008 and i am trying to install SQL Server 2005 full version,after some steps-

ERROR :

SQL Server Setup failed to obtain system account information for the ASPNET account. To proceed reinstall the .NET Framework, and then run SQL ServerSetup again.

This Error occurs at Report server installation option wizard for installing Default Configuration.

Please help to rectify and install the SQL Server 2005.
