Error creating Mysite if Mysite-Host not on the root

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hey guys,

i've got a small MOSS setup with one Webserver and one SQL05 Server.
My Problem is, if i create the Mysite-Host on the root of my Website
like http://domain/, than the Mysite Creation is working. But if i put
the Mysite-Host on a subfolder like http://domain/MySite/, than the
Mysite creation fails. In the eventlog i get the following error:
"Value does not fall within the expected range"

Any ideas?

Regards, biba
