[ExchangeList] Exchange and Antigen

Anyone know of any issues with the new Antigen download today?

My Exchange 2k server had an issue-

The info store appeared as unmounted in ESM and users couldn't access their mailboxes.

However when tried to right click and mount the store, the "mount" option was grayed out.

The SA and Info store services were running the whole time.

There was nothing logged in the event log except that Exchange was in the middle of an Antigen download.

ANyone have any ideas or heard anything "bad" about the new ANtigen download today?

I know a couple of months back, there was a bad Kapserky engine download that slowed/froze mail queues.

Just seeing if this was the culprit.

i've never seen the store unmounted with the services running and nothing logged.

Thanks
