After installing High Encryption pack, clients can't connect
Posted on 2005-04-20
I installed the W2k High Encryption Pack on our Exchange 2000 server because I'm going to need it to allow Linux clients to authenticate to the AD. Since I installed the pack, clients using IMAPS can't check their mail (IMAP works fine). Thunderbird fails with a generic "Unable to connect to your IMAP server" message. Outlook Express also fails and gives the following info:
In the properties for the IMAP virtual server, "require secure channel" is not selected.
OWA+SSL seems to be working fine, though I have a report from our sole Evolution user that Evolution is no longer working for him (and Evolution uses OWA to access Exchange, as I recall). "Require secure channel" isn't selected in IIS either.
What can I do to fix this (bseides uninstalling the High Encryption Pack, since I need it)?
