"The parameter is incorrect." error using netsh http add sslcert

Following the instructions on "How to: Configure a Port with an SSL Certificate" in this link: http://msdn.microsoft.com/en-us/library/ms733791.aspx, I entered this command on the commandline (duh):

C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC>netsh http add sslcert ipp ort:10.141.146.227:7001 certhash=5d48e604007b867ae8a69260a4ad318d2c05d8ff appid= {EDE3C891-306C-40fe-BAD4-895B236A1CC8} The parameter is incorrect.

my certhash thumbprint was taken from the certificate in Certificates(Local Computer)>Personal>Certificates folder.

The appid GUID was generated.

What else is wrong that I need to fix to get this to work?

From stackoverflow

• there were a few things i did that i thought made it work after getting the same "The parameter is incorrect." Error.

  1) restarted machine and did it again. it worked the first time. 2) made sure i was in c:\ and put the command again after restarting didn't work

  i couldn't explain why but i think that maybe both times, there was something else wrong. because the third time this happened to me,

  3) i went through the thumbprint of my CA (not the issued server cert) and copied it again from the MMC and it worked.

  after this happened, i deleted it again (netsh http delete sslcert ipport=0.0.0.0:) and repeated the process using the thumbprint of the server certificate. The darned thing worked again.

  I dunno, just try going through the same thing I did. maybe one of these would work. In the end, i suspect that I entered a bogus space or character in the certhash.

• Looking at the syntax for the netsh command, I saw this example:

  add sslcert ipport=1.1.1.1:443 certhash=0102030405060708090A0B0C0D0E0F1011121314 appid={00112233-4455-6677-8899-AABBCCDDEEFF}
  

  By the looks of it, your problem is that you're doing

  ipport:10.141.146.227:7001
        ^
  

  as opposed to

  ipport=10.141.146.227:7001
        ^
  

• I was getting this error as well when I was just getting started with http.sys. After I ran:

  netsh http add iplisten ipaddress=0.0.0.0
  

  then the netsh http add sslcert commands started behaving properly.
