Why is my iPhone battery draining?

Last weekend I was at PubForum (now E2E Virtualization Conference) in Dublin Ireland. During the sessions I used my iPhone once in a while to check twitter, nothing more then usual. My battery however, was draining really fast. I had to charge my iPhone three times a day and still found myself with an empty […]

Maintenance mode report in SCOM (fixed)

Object, like computers, in System Center Operations Manager (SCOM) can be placed in a maintenance mode. While the object is in maintenance mode no alerts will be generated, as expected.

Exchange 2003 Management Pack Storage Add-On

During an implementation of System Center Operations Manager (SCOM) a customer asked me how he can retrieve information about Exchange mailbox stores for trend analysis. Unfortunately the managemeng pack supplied by Microsoft does not collect the size of Mailbox Stores in the datawarehouse.

The problem was, in short, that after removing the smartcard it was unrecognized.   As a bonus, when a user was authenticated using a certificate on the smartcard, an eject and reinsert was simulated causing the […]

This is fine for most operations in your program, but not when you want accuracy to the millisecond. Although the best […]
