On Thursday, February 23rd, File Transfer Manager (FTM) 5.0 will be
released. When a new file transfer is initiated,
you will be asked to download the FTM 5.0 client. Existing downloads with
the FTM 4.0 will continue, only new downloads are affected.

What's new in FTM 5.0:
Multi-Segment Download Acceleration provides acceleration for high latency
Internet connections. Download acceleration is only used if a file is
greater than 2 MB and download acceleration is set to No Speed Limit in
FTM's options.
File verification. FTM 4.0 validated each data block as files were
transferred. FTM 5.0 goes one step further to verify file integrity by
validating the full file after it has been written to disk.

IVM is a telephone answering machine, voice mail, call attendant, and interactive voice response (IVR) program for Windows. It connects to the phone using a standard voice modem, professional telephony board or even directly to a VoIP service.
This software is an effective voicemail, call attendant, info-line, audiotext or autodial solution for small to medium businesses. For example, IVM can redirect in-coming calls during office hours or act as a PC answer machine and take messages for a number of voice mail boxes after hours. All calls (including those answered by you) are logged with date, time and caller ID. The recorded messages can be played at any time, forwarded to an email address, accessed via the internet or, if necessary, saved for future reference.

IVM can also be used very simply as a computer answering machine. Just run the install file on your PC and it will be ready to answer calls. But, when you are ready, you can explore the advanced key response and programming options to create a sophisticated telephone interactive response system. You will find many exciting ways to use IVM to provide information, serve your customers and save time.

Tight.  Runs as system service with control interface.  Earlier versions were a bit sketchy, not properly handling terminal services logins on the box running the answering machine.  But version 3.0 onwards were great for me.  Emails you MP3 attachment.  Works great with decent hardware.

Problem
After you run dcpromo to demote a Windows domain controller (DC) in your domain, the Microsoft Exchange 2000 Server or Microsoft Exchange Server 2003 MSExchangeAL service starts to log events 8026 and 8260 every 10 minutes. The events are as follows:
Event ID: 8026
Event Type: Error
Event Source: MSExchangeAL
Event Category: LDAP Operations
Description: LDAP Bind was unsuccessful on directory <Fully Qualified Domain Name of Windows domain controller>for distinguished name ''. Directory returned error:[0x51] Server Down.

Event ID: 8260
Event Type: Error
Event Source: MSExchangeAL
Event Category: Service Controller
Description: Could not open LDAP session to directory '<Fully Qualified Domain Name of Windows domain controller>' using local service credentials. Cannot access Address List configuration information. Make sure the server '<Fully Qualified Domain Name of Windows domain controller>' is running.

Solution
If you determine that the issue was caused by the demotion of a Windows domain controller, you can resolve this issue by following these steps:1. Open Exchange System Manager.
2. Expand the Recipients container, and then click Recipient Update Services.
3. Double-click each Recipient Update Service, and then change the Windows domain controller setting to the new Windows domain controller in the domain.
