Just one little tweak to Carl’s helpful suggestion:
While update 11 does indeed require us to reconfigure the IIS connector, there’s some good news: one need not necessarily do a full reinstall (remove/add) of the connector.
If you have done update 5 before doing update 11, and you had already reinstalled the web connector, you can get by this time (after 11) with just doing an update, which you can do from the command line (a little less work in IIS than doing a full remove/add).
For more, see the recent blog entry from Adobe:
For now it just says that if you have applied update 5, you need only update the connector, but the implication is that you did update 5 (or a later one) AND did since do the remove/add, then you need only do the update. I’ll send an email to the author to ask her to clarify that a bit more.
