RPC over HTTP Attempting to ping RPC Endpoint 6001 (Exchange Information Store) on server

Hi Guys,

Have just installed a certificate from GODADDY as we couldn't get RPC over HTTP working through self signed and were told this might be the issue but Outlook still won't connect. After running the test connectivity tool from MS i get the following:

Attempting to ping RPC Endpoint 6001 (Exchange Information Store) on server server.domain.co.uk
  Failed to ping Endpoint

Exchange is 2007 version 08.02.0176.002 so i don't think the RU4 will help and i have tried disabling IVP6 and doing the HOSTS entries as per Microsoft but still comes up with the error above.
This is an Exchange 2007 setup on a new Server 2008 box installed into an SBS2003 enviroment. The Exchange server is not authoritive for the email domain and so we have purchased a second domain to point DNS (autodiscover, owa etc) to the Exchange server and it POP3's from the main domain in the USA.

Any help would be great.

Thanks

Check the valid ports and make sure that the entries are correct.

As eddie stated check your ports.  Also can you get to OWA on this Exchange server, has all the IIS been configured correctly.

I've checked the ports and they work fine (through TELNET and registry checks) and OWA works perfectly.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I've just tried the test again and oddly it made it a step further and now comes up with:
Attempting to ping RPC Endpoint 6004 (NSPI Proxy Interface) on server.domain.co.uk
  Failed to ping Endpoint

I didn't change anything since the last test yesterday.

You might want to forget the last post. I've just ran the test for a second time and it's stopped at 6001.

I can also browse to https://owa.domain.co.uk/rpc and get the username/password prompt

Managed to resolve it.
I have a single Exchange server setup and so i tried adding the IPV4 details into the HOSTS file as shown by MS but this didn't work but i'd also changed the settings for authentication for RPC as advised by someone else but these were wrong so after making RPC correct with Authentication and THEN adding the IPV4 HOSTS entries this then worked fine. The 6004 error was relting to RPC over HTTP not liking IPV6 on the Exchange server but even disbaling it from the NIC won't help as it's in the HOSTS file.
Hope this helps someone else.

Thanks for you time and input though guys!
