Security exception with impersonate true for a webservice

KaNos

Hello world,
I've made a webservice (c# v2) to install in a server IIS 6 on a Windows
2000 last SP. We can use the webservice in local, throw the pages wich
present the methods, with a windows mode connection (<authentication
mode="Windows"/>) if impersonate is false (<identity
impersonate="false"/>). Note that i use the administrator user to be
sure. But when I change impersonate element (<identity
impersonate="true"/>) a system exception is created :(.
Where is the problem ?
Thanks for responses...

on 2000, you must add "act as part of os" permission to the asp.net account
the web service is running under.

Hi bruce and thanks,
but it wasn't the solution. I found this page
http://support.microsoft.com/kb/824308/en-us and my webservice is now ok.
