You should still be able to access the Services MMC and manually stop the service.....I typed in the instructions above. Take a look and try those out. I'm also wondering if Vista's UAC or other security features are preventing NetStumbler from proceeding.
Sorry I prepare for my exams so my replies will late. Ok the results still the same I still got access denied and i tried to find Wireless Zero Configuration service but there no such service in my services.msc.
Thanks S0lo! Alright I'll try that and see if i can see networks.
