One of the drawbacks to extending the schema is that you can only disable,
not delete those changes.  Even rmisa can't help you there; it only removes
the ISA bits from the local machine.
If you believe your schema is hosed and you have backups, then by all means;
go back to what makes you happy.

Hi Jim,
I ment to ask, if applied the ISA's Schema policy to the AD,  before
installing ISA, does that 'rmisa.exe' help in anyway to reset the AD's
Schema policy or just simply make sure we have a backup of the Domain
Controller's system files and restore it from there?

Hi Tom,
I haven't personally seen any of these issues either (lots of Enterprise
installs), but then I've had full control of the installed software base.  I
have seen quite a few "my ISA AD installation seems hosed" entries on the
list, though.

Hi Jim,

Good sleuthing! I would add another piece of advise regarding SP2
installation. Make sure that you install SP2 *before* ISA Server, since
there have been a number of anecdotal reports of things now working
quite right after installing SP2. I haven't had any problems, but I
sometimes get lucky with these things :-)

Thanks!

Found an interesting article today that may answer some of the AD schema
issues that have crept into some hapless folks' ISA servers during
installation into an AD structure.

http://support.microsoft.com/support/kb/articles/Q303/0/77.ASP

Bear in mind that this only affect Enterprise Edition and then only if
you're installing in Enterprise mode (AD-integrated; you know, arrays).

It appears that there is a rare bug in AD that sometimes creeps in when
schema changes are made, corrupting the schema and making installation
of schema-dependent (read: ISA) application problematic at best.

According to this article, the bug was fixed in SP2, but since it's not
'officially' required for ISA installation, it doesn't get applied until
the damage (if any) is already done.

My take on it?  If you're installing ISA Enterprise Edition in
Enterprise Mode (AD-based), then apply W2K SP2 before you run the ISA
schema wizard. If you're not using ISA Enterprise Edition or you're
installing either version in standalone mode, install it anyway.  If
nothing else, it includes the post-SP1 fix that came on the ISA CD.
