problem installing sql reporting enterprise

[pandapark]

Hi

i installed this edition fine on our istanbul server, used an account account2 - worked fine !

tried it on another server - doesn't work
the only difference i can see is through IIS - there are 2 websites, the default website and another one which hosts another application.
the sql dataabses have installed ok, the account has the right permissions in there - was getting absolutely nothing when i tried \\localhost\reports - but i added in the account2 account to be a member of asministrators (local) and then got..........

url:

http://servername:8080/reports/Pages/Folder.aspx

Body: The request failed with HTTP status 404: Not Found.

Home

i have tried changing the tcp host for the default web site to 8080 (so not to conflict with the other website)

same error if i change it back to 80, just

url:

http://servername/reports/Pages/Folder.aspx

I've got SP1 for reporting services on there.............

any ideas ?
thanks
tony
