I'm having a problem with my Foxweb-based website frequently failing (ie. "Site not available" message in IE).  If I look at the site properties in IIS, it _appears_ to be running ok (ie. no 'Stopped' message against the root virtual directory), but all I need to do is stop it, restart it, then everything is ok until the next failure, which may be a couple of hours or days later - there appears to be no pattern which I can see at present.

Foxweb seems to be running ok.

Looking at the NT event viewer, I noticed the following error message which occured when the server was last rebooted...
"The HTTP server was unable to load the ISAPI Application 'C:\WINNT\System32\idq.dll'. The data is the error."

The file mentioned in the message is present.

Because I can easily reset the site from the IIS Management Console, I don't think this is a Foxweb problem, but if anyone could suggest anything that might be causing this (embarrassing) problem, I would be grateful.

TIA
