This can be resolved using a front-end, back-end scenario, but what if you are stuck with a single Exchange server (ie. SBS) in your environment?

On following a few blogs and sites, the solution seems to be to remove SSL requirement for that particular folder in the IIS Manager.  This didn’t work for me though – and I found a lot of people out there with unresoved issues on Experts Exchange etc.

The end solution was to use the ADSIEdit utility to manually stop the Exchange System Manager from using SSL.

The steps are as follows:

1) Install the ADSIEdit Utility (one of the Windows Server 2003 Support tools) from your SBS2003 CD (CD2) using suptools.msi

2) Run a Microsoft Management console (Start->Run->MMC)

3) Open the ADSIedit.msc (browse to the Support Tools folder)

4) Browse through to

Configuration > Services >  Microsoft Exchange > Domain Name > Administrative Groups >     First Administrative Group > Servers > Servername > Protocols > HTTP > 1 > Exadmin

5) Right click msExchSecureBindings, and click Properties

6) Highlight :443: and click Remove

7) Click OK

Restart the Exchange System Attendant and the IIS Admin service

Exchange system manager will now no longer try to use SSL when connecting to the service.

sudo apt-get install likewise-open

However, I got an error message when trying to join the domain:

“Error: Unable to resolve DC name resolving ‘test.example.org’ failed. Check that the domain name is correctly entered. Also check that your DNS server is reachable, and that your system is configured to use DNS in nsswitch.”

Having checked the nsswitch.conf and resolve.conf files, and having followed the advice on the Ubuntu forums about setting a static IP for the domain joining process,  I checked the  nsswitch.conf file again and found that the entries for winbind were missing.

My revised /etc/nsswitch.conf looked like:

# /etc/nsswitch.conf
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference’ and `info’ packages installed, try:
# `info libc “Name Service Switch”‘ for information about this file.
