I have taken a site backup or export(specific site from site collection e.g http://rootsite1/subsite) http://rootsite1 which is in Windows authentication using stsadm Export command. I have successfully restored using stsadm Import command in another web application http://rootsite2 which is configured to both authentication windows http://rootsite2intranet) as well FBA(form based authentication,extend the web application(internet facing site) http://rootsite2). But it is working fine in windows authentication but in FBA mode I am unable to view the sub site.
Could anyone help me to solve this issue ?
