I have setup RPC-HTTP with a self signed certificate. I know this is not the best way as it is difficult to setup but I have got to do it this way.
I know my certificate is all right as I can use it with OWA and ISA is quite happy with it.
We are a really small company and getting money for certificates is not an option.
I have checked and rechecked my settings for RPC against a few different documents from this website and also on the web and it seems all my settings are correct.
I have spent a couple of weeks now trying to get this working on my own by researching and researching but have not found anything that really helps.
I have run ExBPA on my Exchange server and all is working fine, but am getting an error for active directory (added as an image below)
I have also added my RPCDUMP file to this question as well so you can see what's happening.
I can get through the ISA firewall and to the DC when connecting as RPC-HTTP and the DC redirects to the exchange server and asks for the password which is when it falls down.
I have tried a few tests that I found on the web to make sure RPC is setup correctly and apparently it is.
