Windows XP, SP 3 on a IBM T60.
Using same laptop for over one year but never had this issue.
Wireless Zero Configuration service gets stopped every time I put my laptop in standby mode. Workaround was to set the Wireless Zero Configuration service to restart if it fails once.
Reapplying the image with SP2 I had no error, I put SP3 back and no error but after ~one week the same error appeared.
Event viewer logs this error:
