Moss 2007 new site using export/import

[PaulSc]

hiya..after picking people brains please..

We have a moss 2007 farm where we have been asked to a/ create a new site collection then b/ copy the content of another defined site and load it to this new collection, so we have done the following

Create new collection using farm Admin console using a blank site template

run stsadm - o export -url

http://myweb/collection/site

...>

run stsadm -o import -url

http://myweb/newcoll/site

...>

All seems to run fine but when we try to access the new site via

http://myweb/newcoll/site

it gives a 404.. but access via

http://myweb/newcol/site/subsite

it works fine??

anybody seen this sort of scenario before please and able to offer any suggestions ??

Thanks.
