PrimalForms – tool for creating Powershell forms

This is a fantastic free drag-and-drop tools for creating GUI forms in Powershell.  Drag and drop your form objects such as checkboxes, buttons, progress bars etc and PrimalForms will then create the Powershell code for you.

It takes me back to the days of Microsoft Visual Basic forms design – very similar!

Exchange 2003 cluster with Symantec Endpoint Protection (SEP)

After a reasonably painless recent rollout of SEP v11 to our fleet, we’ve come across some issues running it on a Windows 2003 Active-Passive Exchange 2003 cluster. Symptoms: nodes unresponsive, sometimes together, sometimes minutes after the other one – not even blue screened but completely unresponsive, nothing on the console.

Anyway the short of it was that we managed to get a memory dump and learned that system32driverswpsdrvnt.sys had been causing the issues. Doesn’t ring a bell? Well it’s the Sygate Personal Firewall which has now been rolled into Symantec Endpoint Protection, the network threat protection component.

We obviously didn’t want to completely remove AV from our email system if possible, so we modified the installation to only contain the core files plus AV protection (see below)

2 weeks running like this and the problem has not reoccurred.

    CPU usage at 100% – svchost

    I’ve often seen enterprise workstations have their CPU randomly spike to 100% usage for a few minutes, making the machine completely unusable. A quick look at the Task Manager shows svchost.exe being the culprit.

    95% of the time, the below process will fix your problem.

    1. Create a batch file and put the command shown below into it.
    2. Download windowsupdateagent30-x86.exe from Microsoft (http://download.windowsupdate.com/windowsupdate/redist/standalone/7.2.6001.788/windowsupdateagent30-x86.exe)
    3. Download WindowsXP-KB927891.exe from Microsoft (http://www.microsoft.com/downloads/details.aspx?familyid=7A81B0CD-A0B9-497E-8A89-404327772E5A&displaylang=en)
    4. Restart machine in safe mode. Run the batch file, then windowsupdateagent30-x86.exe, then WindowsXP-KB927891.exe
