In cases where this error arises when the IIS is on a different box to sql server, its usually fixed by changing the Active Directory record for the IIS server to say "trust this computer for delegation".
Basically NT domains don't let computers do multiple credential hops, one from browser to IIS, and one from IIS to Sql Server.
However I've just hit this problem at a client install and it doesnt seem to be that.
Can you expand on this at all? How would one change the Active Directory record for the IIS server to say "trust this computer for delegation"?
