Call WebService on Windows 98, random timeout exception

[azerty]

Hello

I develop an application which must call a WebService on a server (develop
with ASP.NET framework)

If I call this application from XP client station, no problem occurs

BUT if i call the same application on Windows 98, sometime everything work
fine, sometime, I have a timeout exception (after 2 or 3 minutes !)

(The init application is written in Delphi language but I can reproduce the
same problem with a small c# windowsForms application)

In Delphi application, I can change with "build const" the framework to call
winsock function, and every framework throw the same error.

with Indy framework, I have more information in code (may be this topics can
help someone to understand the bug )

// If this is a CLIENT
// -------------------
// The server side of this connection has disconnected normaly but your
client has attempted
// to read or write to the connection. You should trap this error using
a try..except.

All this advices seem show the problem is in Windows 98 level and not in
application Level (C# application, Delphi application with native framework,
Delphi application with Indy framework don't work fine)

Do you have meet the same problem ? could you help me please ?

thanks for your help
