authentication Problem with asp.net and java-applet
 

We are having an Intranet based on IIS 5.0 where I need Integrated
Windows authentication:

My Problem:

I have 2 Possibilities:

1) "Windows authentication"

I only choose "Windows authentication" at IIS.

My java applets dont work since Windows SP Xp1a (just Sun-Java)

A java-dialog appears with Passwort-Query
(Passwort erforderlich - Netzwerk) Firewall/Bereich/Schema


2) "Windows authentication" AND "Anonymous access"

I choose "Windows authentication" AND "Anonymous access" at IIS

My java applet work (I think they need anonymous access), but then I
have

a problem with my asp/asp.net scripts.

The user to connect to the database is not the windows user, then it
is then IUSR_MACHINE.
(I use Integrated Security=SSPI)

Do you have any idea ?

1) Can I config java applets to work with windows securtiy

2) Can I get the real windows-user with asp/asp.net when I choose both
authentications (not just IUSR_xy)

3) Are there any changes in the IE-Settings necessary ?

thanks
paul

p.s.:
I use i.e. then Frontpage 2000 Applets (fprotate.class,fphover.class)

p.p.s.: the problem exist since Windows XP SP1a (no MS VM any more)
