Hi,

This is Rahul. Please help me to detect my problem. The problem description is the following:

I have created a Software for TOLL PLAZA i.e. TOLL Management System. There are multiple Lanes in one TOLL Plaza. and i have installed my software on each and every Lane of PLAZA separately. I have used SQL Server 2005 as a database for store transactions. and I have also installed SQL server separately on each and every Lane of Plaza. so that, Transactions data and all vehicles related data such as Video, Image and others data of every Lane of PLAZA might be stored on the same machine individually. There is also a main server i.e. PLAZA server on which all Lanes data updates. All of the Lanes systems are in the network. i have used WCF service for the transactions of data. now the problem is that my application that i have installed on every Lane log out within 2-3 days automatically suddenly. See that suppose there are 12 Lanes . now all lanes log out one by one means First 1 log out , then 2 then 3 then 4.... etc as well as they are in network sequentially. and I see an error .... error is due to:

tsclient\a.dll

I don't know what the problem is. why are all lanes of Plaza logging out sequentially. i am facing this problem many times but i don't get any idea. i thought it may be problem of VIRUS. and i scanned all the systems but, i have no success.

Please help me anyone to detect this problem ASAP.
