An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll

I'm working in a Windows project (done a long time back by Visual Studio 2003 by .NET 1.03**). When I try to run some forms I am getting a strange error:

An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll

Additional information: Exception has been thrown by the target of an invocation.

The inner exception is this:

Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Web.Services.Protocols.SoapException: Server was unable to process request. --> Value was either too large or too small for a UInt16.

--- End of inner exception stack trace ---

This has happened mostly when the variable is initiated (this code was sent to production many many times without this issue).

Is there solution for this?

(Is this caused by corruption of the framework itself?. Further, my PC have all the frameworks up to latest version.)
