Can't logon SharePoint in SBS 2008

We are running sbs 2008. We can access OWA and remote computers. However we can't logon SharePoint. If we click Internal Web Site, the logon screen popup. After entering username and password 3 times, we get "Internet Explorer cannot display the page". I have tried domain\username or username@dimainname.com. We have this problem in the LAN or the Internet. I also found this event in the sbs 2008.

Log Name: Application
Source: Windows SharePoint Services 3 Search
Date: 10/26/2010 1:55:25 PM
Event ID: 2436
Task Category: Gatherer
Level: Warning
Keywords: Classic
User: N/A
Computer: SBS2008.chicagotech.local
Description:
The start address <sts3s://remote.chicagotech.dyndns.org:987/contentdbid={779c9c61-9811-47fb-852c-2463c2c7badc}> cannot be crawled.

Context: Application 'Search index file on the search server', Catalog 'Search'

Details:
Access is denied. Check that the Default Content Access Account has access to this content, or add a crawl rule to crawl this content. (0x80041205)

I have added DsiableLoopbackCheck and URLs to the registry as shown below.

I do have a firewall in the router. However, port 80, 25, 443 and 987 are open. If I run IAMZ, I will receive a warning mentions that I need to open those ports manually. I can telnet those from the Internet. I will send you the screenshot.

Here are the screenshots.

I can access RWW using https://chicagotech.dydns.org/remote

I can logon RWW and access OWA and connect to a computer.

When I click on Internal Web site, the logon screen popup.

When trying to logon, I get this page. I have tried domain\username or usernam@chicagotechdyndns.org or username@chicagotech.local.

From the screenshot you could see RWW actually tries to access the following URL for companyweb

https://chicagotech.dyndns.org:987

I think this URL might have not been mapped from the firewall on your router to https://remote.chicagotech.dyndns.org:987 on your SBS server. You may need to configure on this firewall to forward all the requests to 987 (https) to your SBS 2008 server to test. It's very similar a reverse proxy settings on ISA 2006 or TMG.

Also, please run Internet Address Management Wizard again to confirm that you configure chicagotech.dyndns.org other than remote.chicagotech.dyndns.org in the wizard for your public URL.

By default SBS will prefix your domain name with remote and use this as your public URL to access resources such as OWA, RWW, TSGateway, the Exchange AutoDiscover service, etc. If you want to use a different prefix or no prefix at all, click the "Advanced setting" link. This will open the window to let you customize your domain name.

You should avoid using a blank or “www.” prefix as this may prevent you from following our best practice of hosting your business website off of the SBS box.
