FileSystemWatcher: Analyze missing events/diagnose file system events [NOT programming]

$

Hi All !

I have a management app running on Server 2008 (R2), which uses the

FileSystemWatcher object in .Net to monitor file change evnts. There are

two servers, where it does not work, like on the other [2008 R2] servers and

re-install is not an option.

This is a long running app, which is in use for several years now and it

is likely NOT a programming related thing [the same program behaves

differently on the two mentioned machines].

The underlying general behavior :

a) monitoted app opens log file, keeping it open. It makes writes from time to time.

b) monitoring app uses filesystemwatcher and get notified about opening/updating

the file once. It then polls the file via FileInfo.Refresh on a timer.

b) causes the filesystemeventwatcher to raise new events on the

"intact" servers, while NOT on the "damaged" servers.

I want to find out, what in the driver chain/underlying filesystem

could cause this behavior.

Any help will be really very great!

Thanks so far and

best regard
