RPC / HTTP - Directory not connecting

Hi All,

I have an exchange server here that is not connecting with RPC properly.

I have, in the past, successfully configured server with RPC/HTTPs (generally on SBS machines)

Now, this server is not an SBS server, or a DC - and this is where I think my problems have begun.  The server is the only exchange server in the site.

with outlook /rpcdiag I can see that;

Mail connects fine with HTTPs (3 times)
Directory does not connect at all (twice)
Referral pops up every now and then, but I can't see if it connects.

Now, If i connect the VPN, I can see that directory connects with TCP/IP - which is obviously the problem.

I followed the amset guide, and the petri guide to get this thing set up - but I am obviously missing something integral.

Any help you can give would be much appreciated

thanks

Where is the closest global catalog server to the Exchange server? Is there one located in the same site?

Maybe you can try specifying the client to use the closest GC.

The lack of directory connecting usually means that the registry settings aren't correct. Either they are missing, or it cannot find the domain controller using the information that you have put in the registry.

The kb article to set the GC doesn't apply to RPC over HTTPS - the registry settings for the feature do that work.

Hey Sembee,

Thanks for coming,

The registry settings I used were from > http://www.amset.info/exchange/rpc-http-server.asp

I might try rebooting the server, and if that does nothing then I will try pointing it at another GC

Unless you have any other suggestions?

I should qualify that a bit;

This is on my Exchange Server

exchange-server:100-5000;
exchange-server:6001-6002;
exchange-server.domain.local:6001-6002;
dc:6001-6002;
dc.domain.local:6001-6002;
exchange-server:6004;
exchange-server.domain.local:6004;
dc:6004;
dc.domain.local:6004;
mail.external.com:6001-6002;
mail.external.com:6004;
dc:593;
dc.domain.local:593;
exchange-server:593;
exchange-server.domain.local:593;
mail.external.com:593;

This is on the DC listed in the above edit

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters

Create a new key of type REG_MULTI_SZ

Name: NSPI Interface protocol sequences
Value: ncacn_http:6004

Wait, I think I got it,

The DC I was pointing at is/was a windows 2000 server

I added the reg_multi_sz remotely (from the 2003 server) and didnt notice till I tried to recreate it from the 2000 machine

Is there any way around that?

If not, do you object to a delete refund?

Thanks

Used my settings I see.

You MUST use a Windows 2003 GC/DC. If you don't have a Windows 2003 DC then you cannot use RPC over HTTPS.

Which is how I found the problem

Thanks Simon,
