The problem can occur only when the data source is opened under the Microsoft Internet Information Server (IIS) or a Microsoft Windows NT service but not under a logged-on user account.
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.
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.
