Cannot use SSL port 443 From 2008 server Cannot connect to any ssl web site.

I have a very strange issue with a 2008 server I first noticed this problem when Mozy backup which is used for some files stopped working. I then found I could not reach any ssl site or even the internal interface of my sonicwall. I have run wireshark and found 443 bound to  the system process.  When I try and access a ssl site I can see a SYN going out to 443 then ,a return SYN with: Header checksum: 0x0000 [incorrect, should be 0x2dec] RST packet and so on. I have been trying to identify what on the server is causing this conflict.  Any Ideas?

Might be malware, but more likely something in the Firewall?
What router / firewall do you have?  Some grab port 443 for remote management of the router itself, so you may need to reconfigure the port for remote management if the router.

Test for port 443 on www.canyouseeme.org to see if it is open and listening.

ASKER

Cant be the firewall because I would be able to access the inside interface via ssl
I also changed the owa port to 444 and tried stopping every service I could.

Everything points to the server it seems. I have the firewall off and symantec endpoint 12 disabled. IIS too
TCP    0.0.0.0:443            0.0.0.0:0              LISTENING       4
 TCP    [::]:443               [::]:0                 LISTENING       4

process 4 is system



Have you re-run the fix my network wizard again yet?
Hello  

I have run network wizard repair

I used netsh to reset the tcp\IP config to the defaults, this worked

Seems something messed up the IP stack  http://support.microsoft.com/kb/299357

note the commands are different for 2008

I solved it myself
