lsass.exe starts maxing CPU after ASP.NET web app deployment

After deploying a new build (mostly changed DLL's) of an ASP.NET web app the CPU on the server is now jumping to 100% every few seconds and the culprit is lsass.exe. Do you think that the deployment of the asp.net web app to the server and this problem are related? (or a coincidence that it happened at the same time?)

More info:

This is the first time that I've done the build on a Server 2008 x64 machine. Previous the builds were done on a Server 2003 x86 machine. Target is 'Any CPU' so should work on either. Deployed to server is Server 2003 x86.

I've searched the web for more info on this and have confirmed that the process is lsass.exe (first character a lower case L and not an upper case i) so ruled out the virus version. Found some docs relating to a Server 2000 bug but doesn't apply here.
