Hi,

I have a .NET webservice which has been running OK on a W2000 machine. The web.config file was enabling impersonation:

<identity impersonate="true" userName="MrX" password="somepassword" />

The machine has now had DNS and Active directory installed and I'm now getting the following error:

The XML file c:\....\config\machine.config could not be loaded.
 Either the required impersonation level was not provided, or the provided impersonation level in invalid

It seems as if the username/password supplied are still valid - if I use a non-existent username or invalid passord I get a message saying the windows token could not be created with the supplied credentials. The account used is an Administrator level account but, even with pemissions to the .NET folder opened right up, I can't get past this error.

I read somewhere that there was an issue with .NET when a machine was converted to a domain controller but this referred to .NET 1.0 and said there was no longer an issue with 1.1. FWIW other pages not using impersonation are fine...

Any suggestions gratefully received,
Viv
