SYMPTOMS
When you attempt to access a Microsoft FoxPro database from an Internet Information Services (IIS) 5.0 Active Server Page (ASP), the following error message occurs:
CAUSE
For access to be granted to the Netware File System, IIS must pass credentials with the appropriate permissions for the databases that are attempting to be accessed. By default, IIS attempts to pass credentials for the IUSER_MachineName account.
NOTE: The IUSER_MachineName account appears as though it is being used by IIS 5.0 Web sites that are being run out of process. However, the IWAM_Machine Name account impersonates the IUSER_Machine Name account. Therefore, the IUSER account is the only account discussed in the following resolution.
Netware uses the Netware Directory Service to authenticate users to its servers. To access any file systems, a legitimate account for the credentials that are being passed must exist on the Netware server.
RESOLUTION
To resolve this problem and allow access to Microsoft FoxPro databases on a Netware 5 Server that is running only TCP/IP, perform the following steps exactly:
- On the IIS computer that is attempting to communicate with Microsoft FoxPro, install Novell Netware Client for Windows NT (Required). During setup, choose a custom installation, choose to install into an NDS system, and only choose ip for the protocol. Do not install Workstation Manager.
- On the Windows 2000 IIS 5.0 computer, open the Computer Management Snap-in (under Administrative Tools). Under Local Users, right-click the IUSER_Machine Name account, and then click Set Password. Change the password, save it, and then close the MMC.
- In the Internet Services Manager, do the following:
- Right-click the server name (for example, MYWEB01) under Internet Information Services.
- Click the Edit button next to WWW to open the master properties.
- On the Directory Security tab, click the Edit button next to Anonymous and Authentication methods.
- On the Authentication Methods tab, click Edit under the Anonymous section to open the Anonymous User properties.
- Click to uncheck the option for IIS to control the password, and then enter the password that you changed in step 2.
- Create an ODBC System DSN by using the Microsoft dBase VFP driver. Give the DNS a name and configure the following settings:
- In the Database type section, choose Free Table Directory.
- For the path, enter the Universal Naming Convention (UNC) to the Netware File System where the database resides.
- Under options, click to uncheck the Fetch Data in Background setting.
- Open the Netware Administrator located on the sys: volume in the Public\WIN32 folder of the Netware 5 Server. In the root of the container where the server exists, create an IUSR_Machine Name account that is identical to the one on the Windows NT Server computer. In the properties for that user, click Password Restrictions, and then make sure that only the Require password option is checked and nothing else. Click the Set Password button and set it to that of the Windows NT account. Do not require passwords to be changed on the Netware system.
NOTE: This is the most crucial step to the entire process. - In Netware Administrator, open the properties for the newly created IUSER, click the Rights to files and directories tab, and then add the appropriate permissions to the database files that need to be accessed. Give at least Read permissions, unless changes will be made through the Internet, which requires all permissions except Supervisor and Access Control.NOTE: For access to be granted, the Netware Server requires that both the .dbf and .cdx files exist in the same directory. If only the .dbf file exists, the error message appears.
Test your application to see the data that you are attempting to access.
WORKAROUND
If the above resolution is not satisfactory, a workaround can be produced that is typically used in older Netware versions. By using GSNW, a connection to the Netware 5 Server can be established with the IPX/SPX protocol. Please note, however, that this requires that IPX be added to both the Netware 5 Server and Windows NT Server.
For installation instructions for the GSNW, please refer to the Windows 2000 End-User Manual.
