New Post: 403 error when feature is actived on server 2008 r2

Sir,

I've deployed your solution to a sharepoint 2007 farm running on server 2003 r2 (32 bit) which is an anonymous site and it is working great! but now we migrated the content db's to an new moss 2007 farm running on server 2008 r2 (64 bit) and it gives 403 FORBIDDEN errors when opening the website. When i deactivate the feature on the web application then the site works as a charm. Any idea?? we would really like to keep your project active as it worked on the old farm.

Thanks!
