Connection String to connect sql database
When a file RECORD_HOME.asp is run from IIS 5.1 server (localhost) with folowing code to connect sql database
set con=Server.CreateObject("ADODB.Connection")
con.open "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=Record;Data Source=Home-PC\sqlinst"
the IE 6.0 displays the following error
-------------------------------------------------------
Technical Information (for support personnel)
Error Type:
Microsoft OLE DB Provider for SQL Server (0x80040E4D)
Login failed for user 'HOME-PC\IUSR_HOME-PC'.
/sk/RECORD_HOME.ASP, line 40
-------------------------------------------------------
Sql Instance- sqlinst
Server- Home-PC
Database Name- Record
Server Authentication mode- Wnindow Authentication
The file is stored in sk folder which is resides in wwwroot folder. The same connection string works fine in VB6 project. What will be exact the connection string?

Hi there,
By running with "Integrated Security=SSPI", the connection to the database is made in the context of the calling user. In a VB 6 application, that account is probably your own account which probably has access to the database. In an ASP application, the account used is the IUSR account. You can either grant the IUSR account access to the database, or use SQL authentication in your connection string.
For more details: http://imar.spaanjaars.com/QuickDocId.aspx?quickdoc=395
Cheers,
Imar

I read and found the solution. Thanks for guidence. one more thing i want to know that what will be appropriate data type to store text of length>20000 characters in sql database (memo type in Access database). In sql server database text and varchar data type allows only up to 8000 characters.

Hi there,
That limit only applies to varchar / nvarchar, not to text / ntext. These data types allow up to 1 or 2 Gig of data.
Cheers,
