FIX: RDS error when Web site is run out-of-process
This article was previously published under Q223036
When you run the default Web site out-of-process and use Remote Data Services (RDS) the following error results:
A Runtime Error has occurred.
Do you wish to Debug?
Line: xx
Error: Unexpected error (0x80070558)
To resolve this problem, install MDAC 2.5 or a later version. To obtain MDAC, visit the following Microsoft Web sites.
MDAC 2.8 SP1
MDAC 2.8
To work around this problem, use one of the following methods:
- Run the default Web site in-process.
- Transfer the Web application out of the default Web site into another site.
Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section.
This bug was corrected in Microsoft Data Access Components 2.5.
Steps to Reproduce Behavior
- Save the following code in a text file called RDSBug.asp in the root of the default Web site.
<%@ Language=VBScript %>
<SCRIPT LANGUAGE=VBSCRIPT>
Sub cmdLoad_OnClick
dim df, rs, oTR
set df = ds.CreateObject("RDSServer.DataFactory","http://<webserver>")
set rs = df.Query("DSN=Northwind;","SELECT * FROM Employees;")
tblMain.deleteRow
while not rs.eof
set oTR = tblMain.insertRow
for x = 0 to rs.fields.count - 1
set oCL = oTR.insertCell
oCL.innerText = rs(x)
next
rs.MoveNext
wend
rs.close
set rs = nothing
set df = nothing
End Sub

Test your setup by running the page. If the page does not display data correctly, verify that you have the Northwind sample database installed and that the Northwind data source name (DSN) is set up in your ODBC Administrator. (The Northwind database is installed with the Microsoft Visual Basic samples in the VB98 directory as Nwind.mdb.) If the page still does not work correctly, review the following Knowledge Base articles to confirm that your RDS configuration is correct:

Troubleshooting Common Problems with Remote Data Services
- After you have confirmed that RDS is configured correctly and the page is working, open the Internet Services Manager, right-click the default Web site and click Properties. Click the Home Directory tab. Select the Run in separate memory space (isolated process) checkbox or, under IIS 5.0 or later, change Application Protection to High (Isolated). Click OK to exit the Properties dialog box.
- Open the page again in your browser. The page will return "Unexpected error (0x80070558)".
