RDP clients and ICA clients cannot connect to a Windows Server 2003-based terminal server after hotfix 938759 is applied to the server

Encounter an issue of users being unable to logon to some of our Citrix Servers running on Windows 2003 R2 Sp2 after deployment of the security update (KB2653956, http://support.microsoft.com/kb/2653956)


It seems to be known issue that only affects Windows 2003 server but Not Windows 20008 Servers. The issue can be corrected by applying the hotfix listed in the KB below.
http://support.microsoft.com/kb/958476


Interesting that this is not corrected by Microsoft in the fix to prevent the issue from affecting the Windows 2003 Server and instead provided a hotfix to correct those that maybe affected

Removing Delete Computers from SCOM View


There will be times when the SCOM agent has been a decommissioned server but after some time, this object is still displayed on the SCOM Computers view.

If removal is required, the SQL statement below will enable you to do so

UPDATE [OperationsManager].[dbo].[BaseManagedEntity] SET [IsDeleted] = 1   WHERE [DisplayName] LIKE 'servername'

SCOM SNMP Threshold Type


SCOM SNMP monitors/rules creation could be easy to create but it could be also a pain to configure the thresholds.
The SCOM Console makes assumption that whatever is being created for rules and monitors thresholds as strings.
Hence, when we have a need to have a threshold which requires the a numeric comparison such as greater than or less then, the string value her will not work.


To work around this, either you can export the management pack and start editing the XML or the easier way out which I prefer will be the below procedure
1)      export the management pack to XML
2)      Use the System Center Operations Manager 2007 R2 Authoring Console (http://www.microsoft.com/en-us/download/details.aspx?id=18222) open the exported MP in step 1. Navigate to the monitors on the left window


3)      Select the correct monitor and then right click, properties and configuration.

4)      Under each >>>XpathQuery and >>>value, you will see >>>@Typ. You will need to change 4 similar attributes like this to Integer. (Refer to screenshot above for sample)
5)      Once this is completed, save the modified management pack.
6)      Re-import the management pack into SCOM.
