Hi Ramil

could it be this

When specifying the ISAPI handler, you can use the registry key,
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSOAP\SOAPISAP, to change the default
values of the following three configuration variables:


a.. MaxPostSize - the maximum size of the SOAP message that you can POST
to the ISAPI handler. While this setting help you to keep hackers from tying
up your service by posting extremely large messages, you may need to
increase the default size (100 KB) if your service accepts large SOAP
messages.
