Overview
Use the Microsoft Exchange Server User Monitor to gather real-time data to better understand current client usage patterns, and to plan for future work. Administrators can view several items, including IP addresses used by clients, versions and modes of Microsoft Office Outlook, and resources such as CPU usage, server-side processor latency, and total latency for network and processing. Works with Microsoft Exchange Server 2000, 2003, 2007 and 2010.

Everything from Assessments to Stress Test Tools.  Check it out… http://www.mcafee.com/us/downloads/free-tools/index.aspx

Turn off “Check for publisher’s certificate revocation” & “Check for server certificate revocation” options on the machine you are starting the EMC on.

1. In Windows Internet Explorer –> Tools –> Internet Options –> Advanced tab
2. In the Security section, uncheck the two options “Check for publisher’s certificate revocation” & “Check for server certificate revocation”

Pleae Note:  This is a security option and unchecking this represent a risk unless the machine is in a secure environment, please be aware this.

By default, the clients computers get their time from a Domain Controller and the Domain Controller gets his time from the domain’s PDC.   You can set the PDC to synchronize it’s time with an external source by doing the following:

  • First, locate your PDC. Open the command prompt and type: C:\>netdom /query fsmo
  • Log in to your PDC Server open the command prompt and Stop the W32Time service: C:\>net stop w32time
  • Configure the external time sources, type: C:\> w32tm /config /syncfromflags:manual /manualpeerlist:1.pool.ntp.org,0.pool.ntp.org
  • Make your PDC a reliable time source for the clients. Type: C:\>w32tm /config /reliable:yes
  • Start the w32time service: C:\>net start w32time
  • The windows time service should begin synchronizing the time. To review your changes check the configuration.  C:\>w32tm /query /configuration
  • Remember to check the Event Viewer for any errors.

Note: UDP port 123 must be allowed inbound

Ever want to know who is logged onto what. Microsoft PSTools is great for this and you can seach by username or computername.

Usage: psloggedon [- ] [-l] [-x] [\\computername | username]

Displays the supported options and the units of measurement used for output values.
-l Shows only local logons instead of both local and network resource logons.
-x Don’t show logon times.
\\computername Specifies the name of the computer for which to list logon information.
username If you specify a user name PsLoggedOn searches the network for computers to which that user is logged on. This is useful if you want to ensure that a particular user is not logged on when you are about to change their user profile configuration

SMTP Queue Utility

Posted: October 24, 2011 in Systems

Often an SMTP queue can be flooded by thousands of non-delivery reports (NDRs) due to spam; and sometimes it can be caused by undeliverable email that has been mistakenly auto-generated.

Clearing the SMTP queue usually involves deleting the files in the queue directory through Windows Explorer or a del *.* command — but there is a better way to handle the problem. One way that works directly with Exchange Server instead of through the file system is a command-line utility called AQADMCLI.

You can use this to delete all emails to postmaster…

aqadmcli  “delmsg flags=SENDER,sender=postmaster@domainname.com” 

 If the problem persists you can change settings in Exchange to auto filter the domain or ultimately use a 3rd party email filter and only allow smtp from that filter.
