Installation problem with php_imap.dll

I am installing Apache/2.0.47 (Win32) PHP/4.3.2 under Win98 using php4apache2.dll. When starting Apache, I get the following error: Unknown(): Unable to load dynamic library 'c:\php\extensions\php_imap.dll' - A device attached to the system is not functioning. The extension_dir is specified as follows: extension_dir = C:/php/extensions/ If I change the extension directory to the wrong path on purpose, I get the error that the module can't be found. Other extensions such as php_gettext.dll, php_ldap.dll, etc., load properly. PHP is finding the module, it just can't run it. If I comment out php_imap.dll, Apache loads with no errors and functions properly. I would appreciate any information anyone has.
