|[KB_43] - Microsoft OLE DB Provider for ODBC Drivers (0x80004005) [Microsoft][ODBC Microsoft Access Driver] Disk or network error.|
When trying to open on our our scripts in a browser an ODBC error is returned stating "Disk or Network Error". The Microsoft OLE DB Provider for the Microsoft Jet database engine may also return an "Unspecified error" (error code = 0x80004005) message.
When trying to connect to an Access .mdb file, an ODBC error is returned stating "Disk or Network Error". The Microsoft OLE DB Provider for the Microsoft Jet database engine may also return an "Unspecified error" (error code = 0x80004005) message.
The problem can occur only when the data source is opened under the Microsoft Internet Information Server (IIS).
Jet creates a temporary file when the engine is started. In doing so, it first checks the TMP environment variable and uses that path to define where the temporary file is created. If it doesn't see a TMP environment variable, it looks for the TEMP environment variable. If TEMP is not defined, it then uses the Windows folder (\WINDOWS or \WINNT).
If TMP/TEMP is defined but points to a nonexistent folder, the error occurs.
Moreover, when opening the Access database through IIS or a Windows NT service, and when IIS or the service is running under the local system account, the TMP or TEMP system environment variable is used. When the Web services or Windows NT service are started using a user account, the TMP/TEMP user profile environment variables is used.
Define a TMP or TEMP environment variable and assign the variable to an existing folder. If you are accessing the Access database from IIS, be certain to check the system environment settings rather than environment variables of the logged-on user. Also ensure that the IUSER anonymous IIS account has access to the temporary folder.
You must restart the computer after changing any environment variables.
Environment variables are set under Windows NT 4.0 by going to the Control Panel and clicking System and then selecting the Environment tab. On Windows XP / 2000 / 2003 Server systems you can set the environment variables by right clicking on the "My Computer" icon and selecting "Properties" from the list of options... then select the "Advanced" tab and click the "Environment Variables" button at the bottom of the properties box.
