SBS 2011 Environment running exchange 2010   SP3.    

Computers can browse to Google and a few other random sites but mostly just get a certificate error pointing back to my own server along with the IIS7 splash page.   I realized no matter what domain I type, if I put /owa at the end of it, it will load my web app page.   DNS however does resolve in NSlookup regardless of what site I try.  

Also Outlook is able to receive emails but is not able to send.  It keeps telling me my remote server is rejecting the message from being delivered.   Error is remote.(domain).com #550 5.7.1 Unable to relay ##

There weren't really accurate topics on here so if this has to be moved I understand. 

I'm wondering if maybe some IIS bindings / certificates got messed up and that's why its redirecting me there every time.

Thanks

FYI to add to confusion I'm using Self signed certs from the server running as CA. 

I recommend that you post this in the SBS Forum:  http://social.technet.microsoft.com/Forums/en/smallbusinessserver/threads

UPDATE: 

I have reset the routers config and internet is working again.  No more splash page!!  
Email is flowing both ways again.  

Still need to figure out which is the best route to go for establishing folder redirection to work on the new server.   A few clients are still pulling their redirected folders from the now non DC old server.  :/  New redirected folders show up but I think its a permission issue somewhere according to logs. 

Thankfully I figured the biggest part of this out.
