yeap. Which doesn't mean that you should now hurry and simply perform SID-History cleanup in your environment without doing the necessary investigations. Your environment might still heavily rely on SID-History without you realizing it...
Even if you've done your re-acling on all existing fileservers and you've got nothing left of the migrated NT4 domains, it is not uncommon, that companies that have leveraged the ADC during an Ex5.5 to E2k Migration still have loads of legacy SIDs on their Public Folders and even on many of their mailboxes. You might be fine from a FileSytem point of view - but Exchange 2000/2003 (depending on how you've migrated) is a totally different story. The newer migration tools will now also tackle PF re-acling and I'm sure that someone else will come up with some other nice scripts in the near future - but you'll definitely have to watch out for this. /Guido -----Original Message----- From: Roger Seielstad [mailto:[EMAIL PROTECTED] Sent: Mittwoch, 27.

In other words, a nested group pair, where both groups have SID history defined, takes 4 token slots? Roger -------------------------------------------------------------- Roger D.

There is no workaround apparently, this is behaviour by design. The problem I have with this is that, even with nesting, the "problem" accounts are members far few than the 1000 groups mentioned in the KB article. This is still open with PSS. Obviously, we have a workaround to the problem, but it is frustrating not knowing the true cause behind the issue. The only thing we know is that it has "something" to do with the size of the access token, but no real detail. Anyone come across the same (or similar) problem? Any pointers?
