I have come across a unique issue on Windows XP.

Scenario occurs when an XP users visits the intranet site fo the first time.

The mp_insertusers sp dosen't get fired automatically.

This works perfectly fine for users running windows 2000 for a new users. Registration happens automatically calling the relevant sp to insert the users details.

Also for users running Windows XP, sometimes they are prompted for their windows userid and pwd although windows authentication is enabled and enable anonymous access is checked.

I would like to know at what point is the check happening or where exactly is the check happening in the code to check if the user already exists in the mp_users table.

And if not, then where exactly is the insert users sp being called.

Where exactly are these checks happening and where are the users pwds getting encrypted. Are these encrypted pwds the actual windows pwds for users or randomly generated encrypted pwds.

Any help would be greatly appreciated.
