Question

Access denied when connecting to SQL Server 2005 Standard Edition database from ASP script

Asked by: mike99c

Hello,
I have a SQL Server 2005 Standard Edition database on a Windows 2003 IIS6 server.
I have taken a copy of another database from another server and restored it within this server. The previous SQL server database was an Express edition.

When I try to run my ASP test connection script, the page hangs rather than display a confirmation statement.

I ran a trace of all the server events using Filemon and the following line kept appearing:
22:36:03 PM       w3wp.exe:6100                OPEN    C:\Program Files\Microsoft SQL Server\90\Shared\instapi.dll   ACCESS DENIED MyComputerName\IUSR_theiusrname

Although I have only copied databases between SQL server Express editions, I have never experienced this issue before. I have never had to apply permissions to any folders to get the connection to work.

The database has a user which has full owner permission. This is how I have always done it in the past. I have attached the ASP connection script so you can see what I am trying to do.

Many thanks

Const const_SQLDatabaseName = "testdatabase" 
Const const_SQLuid = "sqlusername"   
Const const_SQLPassword = "sqlpassword" 
 
response.write "<p>Start connection</p>"
Set oConn = Server.CreateObject( "ADODB.Connection" ) ' 
with oConn
	.Provider = "SQLNCLI"
	.ConnectionTimeout = 1000  
	.CommandTimeout = 1000 
	.ConnectionString = "server=.\SQLEXPRESS;database=" & const_SQLDatabaseName & ";uid=" & const_SQLuid & ";password=" & const_SQLPassword
	.Open
end with   
 
response.write "<p>End connection</p>"
 
oConn.Close
set oConn=nothing

Following on from my post. I noticed that the Authentication mode was set to Windows Authentication only. I have since changed this to Windows Authentication and SQL Server Authentication since we are connecting to the database using SQL Server Authentication.

I restarted the server but still have the same problem.

I have some more information which may be of use.

If I leave the script running for a while then the following output occurs.

Start connection
Microsoft SQL Native Client error '80004005'
SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF].
/dbconnect.asp, line 22

Ok I managed to find the solution in the end.

The server name in the connection string had the wrong SQL server name. We carried over the server name from the previous SQL Server Express server. All works fine now.
