I'm running SBS 2000 w/Exchange SP3, ISA 2000 SP1, W2K
SP4. I have OWA running over SSL and I had IMAP running
over SSL. I installed the MS03-039 security update for
the RPC bug and restarted the server, then I installed
MDAC 2.7 SP1 and restarted the server. After the restart
the Exchange Information Store didn't start up properly
(not sure if it came up after the first restart or not).
I restarted the service and it came back up. Then I
noticed that I could no longer use IMAP externally. I
get the following error:
"Unable to connect to the server"

However, IMAP access still works over SSL when I am
logged in to the server.

Also, when I try to change my password in OWA I get the
following error after entering domain, id, new password,
old password:
"Error: An invalid Active Directory pathname was passed"

This also worked before the two updates were installed.
And everything else in OWA appears to be working fine.
I've checked all the settings in ISA, and they seem to be
exactly as they were before the problems started. I've
restarted the IIS Admin a couple of times, and I restared
the entire server a couple of times.

Any help is very much appreciated.
