DOCUMENT:Q142681 03-MAR-2001 [iis] TITLE :IDC Script Fails to Connect to Database PRODUCT :Internet Information Server PROD/VER::1.0,2.0 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Internet Information Server 1.0 - Microsoft Internet Explorer version 2.0 for Windows NT 3.51 - Microsoft Internet Explorer version 2.0 for Windows NT 4.0 ------------------------------------------------------------------------------- SUMMARY ======= When you try to run an Internet Database Connector (IDC) script file from a Web browser, the following error messages (or similar) occur: In Internet Explorer 1.0: The server considered the request for http://YourWebServer/YourScript.idc?' an invalid request. In Internet Explorer 2.0: Unable to open http://YourWebServer/YourScript.idc?. The site reported an invalid request. The library Odbc32.dll could not be loaded to perform the query. Make sure ODBC has been properly installed on the server. CAUSE ===== A possible cause for these error messages is insufficient Windows NT File System (NTFS) file permissions for Odbc32.dll. ODBC32.DLL is located in the nt_root\System32 directory. By default, the group EVERYONE has Change permissions (RWXD) on this directory and the files created in this directory. If this default has been changed, there is a chance that when Odbc32.dll was copied into the System32 directory it did not receive the "eXecute" permission that Internet Information Server (IIS) needs to run the DLL for the Web browser. RESOLUTION ========== To resolve the problem, either restore the Change permission for the domain group Everyone on Odbc32.dll, or grant the eXecute permission for any account that you expect to be used to run IDC scripts from a Web browser. Typically, this includes the anonymous logon account that IIS creates for you during installation (IUSR_machine_name).
