iis security : Annonymous account using domain account

Greeting,

We have an IIS 5 web app in dev, 2 sites, both also using secured
(SSL). They refering to same physical folder. 2nd site certificate is
bit special, required smartcard.

Both web app (sites) settings are identically same, except the 1st
is using "Script & Executable" permission while 2nd only "Script".
Some of the folders are using a domain account as anonymous access. So
far (in past) so good, they behaved as expected.

This web server is belong to a domain, with partial communication
allowed to the domain controller (blocked by firewall or closed,
whatever). There are the "unable to locate DMC" of NetLogon in the
event log once awhile, no big deal.

However nowaday, the 2nd site giving "Access is Denied" error from
those anonymous access using domain account. Below are the findings:
- HTTP 401.5 in IIS log
- W2SVC logged bad username or password of that particular account.
- BUT 1st site with the same setting (except the special cert) behaved
no problem!

The 2nd site been deployed a renewed cert, that's the changes we
awared.
And the worst is nobody know the password for that domain account
anymore.

We tried "Allow IIS to control password", same result.

We don't want to reset pwd, it will break many things.

Anyone familiar with such problem? Any idea or suggestion to resolve

Well, after opened a case with M$, we can try using a vbscript to grab
the "good" password from 1st site.

But due to some internal reason, we are not going to execute this,
although we tested this out fine.
