sudden long boot on Z60m

[liblit]

My two month old Thinkpad Z60M (XP Pro/Zonelab Pro/MS Office 2000/MS Spyware/AVG virus protection), which booted fast two weeks ago, is now taking three minutes or more. It seems to stall as the desktop image appears for almost a minute. Running Task Manager shows svchost taking a little memory occasionally but nothing much. When the taskbar finally appears, the first file that shows in Task Manager/Processes is wmiprvse.exe, if that's helpful. As soon as this loads, bootup proceeds quickly.
I've tracked wmiprvse.exe to the proper directory--Wndows/system32/wbem. There was another version in I32 which I renamed but this didn't solve the problem.
Before this started, I had updated some Thinkvantage drivers and software off the Lenovo site and bought the Diskeeper defrag program that came (lite version) with the machine. But I removed the only major piece of Thinkvantage that was new (Rescue and Recovery) and disabled the other new bits and the Diskeeper at bootup without bootup improving. So I'm stumped.
Any suggestions?
Otherwise, by the way, I love the machine.

Maybe you could try a startup monitor and temporally disable software (don't delete) that is loaded in the taskbar.

I always use this one: http://www.mlin.net/StartupCPL.shtml

Hope this is useful.

Good luck.

After trying registry cleaning and all varieties of tweaks, the solution presented itself yesterday. Got a new update to Zone Alarm Pro and as soon as it was loaded, the lag time disappeared. As soon the desktop appears, I have the taskbar and startup programs loading.
So those of you with Zone Alarm, make sure you get the new update. Be careful about the installation though by the way. I had to do quite a bit of work to get it to take in the first place and ZoneLabs board shows a number of people with problems. Nonetheless, once installed, the results are very positive.
