For templates to available form the “Create Site” link in the Sites Directory, in other words, to create a top level site or site Collection, this must be done from the Portal command line interface. First, copy your new site template to the C: drive of the server:
From here http:///sites/newsite (Your New Site) go to Site Settings | Site Administration | Manage site Template Gallery right-click the .stp file and save it to the server C: drive.
Now go to Start | Run… and enter cmd and click OK. Type cd then past in the following path (you have to right-click and select paste, CTRL+V will not work)
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\60\BIN
Then paste on the following
stsadm -o deletetemplate -title “New Site Template of Your Choice”
Then type IISRESET
This will delete the existing template, if there is one. Now Paste in:
stsadm.exe -o addtemplate -filename c:\newsite.stp -title ” New Site Template of Your Choice ”
Then type IISRESET again.
