We are getting some complaints at another site that a number of people who installed SP1 today have had some of their Services disappear from the Services list (included are Alerter, Computer browser, Net logon, NT LM security support provider, Remote procedure call locator, and Workstation). I updated but still have all my services. I'm curious to know how many of you have noticed the same problem. It would be nice if we could find some commonality among those who dont. Thanks folks.
