If your computer running Microsoft® Windows NT does have a UNC path specification present in the system PATH variable or in the user PATH variable, you may experience problems with Full-Text indexing and Full-Text Search. First, double-check whether you have a UNC path specification in your PATH variable. To do this, issue echo %path% from the command prompt. If you have a UNC path specification, you will see one or more paths of the form \\computer_name\share_name.
The symptoms of these problems may include one or more of the following:
“Unable to load DLL <X:\Program Files\Common Files\system\ContentIndex\ontciutl.dll>. Error 5 - Access is denied.”
Note X refers to the drive letter where your Program Files\Common Files directory resides on your computer.
Two possible solutions to this problem are:
Note After making any of these changes, restart your computer. SYSTEM path changes do not take effect until the computer is restarted.
If you have not attempted to repopulate your full-text catalog(s) after the addition of the UNC path specification(s) in your user or system PATH variables, you can use Full-Text Search. If you have attempted repopulation, you must rebuild your full-text catalog(s) and then repopulate them before you can issue full-text queries.
