Wonderware Intouch Client/Server to CompactLogix Communication fault

[CChulo]

Hi, I've been having problems with my Server/Client based Wonderware (InTouch) application. I'm running 5 THIN Clients of a Windows 2000 Server and connected to 5 AB CompactLogix PLCs. The issue here is I'm getting randomly (every 3 to 4 weeks) a communication fault between HMI and PLC. I can actually Ping my Clients and PLCs from my server alright but can have them talk to each other. It seems to me that once communication is lost I'm having problems with it reinitializing. What can possibly stop my system from reinitializing its communication???. It is important to mention that this doesn't happen all the time, I've made the test of disconnecting my system's switch and then plugged it back in and system reinitializes perfectly. I'll appreciate any kind of input or approach for my situation. Thanks in advance...

Are you reinitializing the PC or the PLC?

The system should initialize it's own communication, but doesn't. The PLC doesn't fault or anything, just don't have communication between the PLCs and the Server.
