Setting Throttling Policies For Cisco Unity

Recently I ran into issues with Cisco/Unity  within the Exchange 2010 environment. I wrote simple script to create Exchange Server Throttling policy based on CISCO’s white paper with their recommended values on the policy. Script can be found on TechNet Scripting Library

Few reminders with Cisco Unity: It is configured to work with EWS.Voice message put into user mailboxes via API , so you wont see Exchange server information within the message headers.  if you are seeing random users not getting their VM, check throttling policy to make sure the recommended values set accordingly.

EWSPercentTimeInCAS               : 300
EWSPercentTimeInMailboxRPC  : 200
EWSFindCountLimit                     : 10000
EWSPercentTimeinAD                  : 100

Create installation media for IFM

There are times, when installing domain controller, you may want to choose install from media option to start with, remote sites Domain Controllers installation. Perhaps bandwidth is the concern. In similar situations we will prepare IFM to use. Log into your domain controller as an administrator. Open Command prompt with your administrator credentials. Click start on the run menu type cmd.exe and press enter and accept any UAC prompt. At the Administrator command prompt Type:

  1. Ntdsutil
  2. activate instance ntds
  3. IFM
