Hi Everybody,
I have a server - three clients multi-project in PCS7 V7.0+SP2.
On the server is Windows 2003 Std.SP2 server OS and on the client is windows XP SP2.
There Users on the Server are Power Users andSimatic HMI user(Client1, Client2 and Client3 are Power Users and Simatic HMI user). ES on the Server and Clients is Administrator user. The project on the ES is dowloading OS Server andthree clients.Thats OK.

MY PROBLEM IS INTERESTING:
These Clients are logoff OS Server Periodically. Then these clients are logon OS server periodically.
The Logoff periodis vary from10 minutes to 16 Hours.
The Logon period is vary from 10 minutes to 1 Hour.
When the client is logoff,The Client is not answer (time out) PING.exe on the Server.
I don't Understand problem.
Why Client is logoff?
Why the client is notanswer ping.exe on the server (timeout)?

Coud somebody give me some sugestions?

Thanks...
