WPA2 in Windows XP

Having recently upgraded my encryption settings on my just about barely-trusty Linksys WRT54GC to use WPA2 I was able to reconfigure my super little MacBook to use this standard with no hassle at all.

However, upon booting into Windows XP (using BootCamp) a couple of days later my wireless steadfastly refused to show any signs of life. After mucking about for a while a eventually remembered I had changed the access point to use WPA2.

Unfortunately, Windows XP (even with SP2) doesn't support WPA2 until you download a hotfix from the Microsoft website. The URL for this is:

It's small download (about 1.5MB), it's very easy to apply, and it even takes a System Restore point before installing.

But why isn't it a Windows update?

Where are SCANPST.EXE and/or SCANOST.EXE?

I sometimes have to deal with customer computers whose Outlook PST or OST files have become corrupted. Very often the fix is to run SCANPST.EXE on the offending PST/OST file. However, every time I go to do this I forget where the two executable files are. Here is where they are on a Vista machine running Office 2007: C:\Program Files\Microsoft Office\Office12 I hope this helps.

WSUS Issues

Was configuring WSUS on a Server 2016 VM for a customer recently and found the performance to be very sluggish and most of the time the client PCs would time-out and throw an error message when trying to check for updates. After much digging on different forums I came across a fix that worked nicely: Open Internet Information Services (IIS) Manager and click on Application Pools Then Right-Click on your WsusPool instance and choose Advanced Settings Scroll down to Private Memory Limit (KB) and change it from the default of 1843200 to 0 which means unlimited. Then right-click and stop the WsusPool and then start it again. Hope this works for you.

SNMP on HPE Aruba Switches

After installing a number of HPE/Aruba CX switches I was finding that they were completely unresponsive to SNMP requests. Went through the config and couldn't see anything... Eventually found that you need to configure this line in order for the SNMP service to run: snmp-server vrf default Don't forget to do a "wr mem" afterwards!
