On my OES sp2 using an NSS volume, i've got some strange problem.

From a map i launch my CAO application an then try to launch a project
with multiple files but it fails on some of my files.
After that i cannot browse my map. So i disconnect the map and reconnect
everything is ok.

If i try to manually browse my directories to see my files it works for a
minute and then freeze and an error message appear that my network
connection is no longuer valid.

My OES doesn't have a replica of eDirectory.

Did someone got some clues about that ?
What kind of parameter have i to check ?

Thanks for help
