Help with a slight profile annoyance

I recently purchased a new laptop with vista installed. After 2 weeks of
having it... whenever I log in... I get the message "No profile found
matching the current network environment! Do you want to create a new
profile?". I have tried following the prompts but it seems to do nothing...
and the next time I start my computer... I get the same message. This is not
a massive problem but it is annoying all the same. Can anyone please help
out a poor computer illiterate person to rectify this? Thank you!
