Question : How to set ISAPI filter priority in IIS master properties dialog box

In WWW service master properities dialog box under ISAPI Filters tab, how can I change a filter's priority.  For a unknown reason, the "Compression" filter (c:\winnt\system32\inetsrv\compfilt.dll) has a priority "*Unknown*".  I have removed it and added it back on.  It is still the same.

I am using IIS5 on W2K os.  Thanks!

You can't.
Filter priority is determined by the Filter itself when it is initially loaded by IIS (in its GetFilterVersion registration function).
