Problem with webservice

Hello

I have a customer who runs NAV 2009 SP1 with SQL 2005 on Windowa server 2008 i have made a codeunit to serve as webservice and there was no problems for a long time. In the beginning the setup was running on a Windows server 2003 now it is moved to a 2008 server and here the problems begins.

The webservice is called from a ASP.NET site and it stil runs with no problems but when i add som new function call to the webservice in the NAV codeunit so the .NET program need to update the ref. there is problems with the ref. login we can type the same login 10 - 15 times with access denied and then suddenly it works.

In the event log on the NAV server there is this error every time a login failes:
