Problem in installing SPS 2007

Dear all,
i solved the problem,when you Un install SPS 2007,before starting new installation,do the following :
1- Un install WSS 3.0.
2- Reboot your system.
2- Delete any site related to SPS or WSS in IIS manager.
3- Install fresh copy of SPS 2007,it will install WSS and SPS portal server as well.
hope this helps.

To make you feel better - I've rebuilt our test environment four times in the last six months (DC, Exchange, SharePoint) and rebuilt SharePoint about six times (Web Server and DB server) as new versions of betas have come out and as I've got things so badly broken that they need to be restarted from scratch.
Good luck.
