Employee portal crashing Navision server

mmax

I am experiencing some problems while using the EP. I managed to setup the communication between Sharepoint 3 and NAS and I can now add webparts in Navision that I can use from my sharepoint site.

When using those webparts in sharepoint sometimes the server is fine but sometimes it causes other Navision users to loose connections ... ? #-o

My configuration is :
Navision SP3
NAvision NAS SP3
Navision EP SP3
SQL 2005
I am using a domain User ID to start the NAS service for which I 've got full access to the Navision db.
I am not using the encryption from the NAS backend to the frontend Server

Any idea on what could be the source of the problem very much appreciated
Thanks
Max
