web site already exist issue?

Question

Hello everyone,

I am using SharePoint Server 2007 Enterprise with Windows Server 2008 Enterprise. And I am using publishing portal template. And I am using command,

stsadm -o restore -url http://machinename:8090/siteabc -filename c:\backup\siteabc.bak

But met with the following error -- there is a web site already exist on "/siteabc". Please specify a new URL or using -overwrite.

How to check whether there is a web site called "/siteabc" already exists? Not sure whether tools like SharePoint Manager could detect this?

thanks in advance, George
