Outlook Anywhere Over RPC - 1.Sep.2008 5:31:55 AM

Morning All,

I have my Exchange Server 2007 SP1 running over RPC for outlook anywhere and this was working all ok.
A recent re-boot has knocked out the function to connect to RPC from a new external client but any exsisting clients are all ok and are still working and being updated.

I have checked all the services are running and nothing has changed with the certificates.

If you have any ideas where i could look that would be great.

It's very strange as the exsising clients are all working (which would seem the server is running) but any new clients to be set up externally (outlook 2007, outlook 2003 etc) cannot connect at all. To get it working i have to bring the laptop in from home, connect it to my network, set the HTTP over Outlook Anywhere and then use it externally again.

If you need any info just shout.

Many thanks

Gaz

Have you confirmed that existing clients are working over HTTPS? There is no reason I can think of why existing clients would work and new clients would not. You could look through the web site logs to see whether anything is logged when they try to connect.

I've right clicked on the outlook icon and have gone to connection status and they are using HTTP.

Where is the best place to look for Logs? IIS logs, exchange logs or even event logs?

I've just checked the IIS logs and found this.

Microsoft+Office/12.0+(Windows+NT+6.0;+Microsoft+Office+Outlook+12.0.6213;+Pro) 401 2 2148074254

and

Microsoft+Office/12.0+(Windows+NT+6.0;+Microsoft+Office+Outlook+12.0.6213;+Pro) 401 1 2148074252

found this support page on MS about 401 errors

http://support.microsoft.com/kb/907273

I've gone into IIS and edited the properties on the RPC. This was set to BASIC so i've also changed the windows auth.

I'm going to try this out now.

Any other ideas?

Exchange doesn't have any logs, other than transaction logs. All logging by Exchange does in to the Event Viewer.
The Event Viewer is unlikely to show anything.
As I wrote above - the web logs - so IIS logs - will show the connection attempts and whether the web server is rejecting it.

Simon.

RPC_IN_DATA /rpc/rpcproxy.dll exchange.domain.net:6004 443 domain\gary <EXTERNAL IP ADDRESS> MSRPC 200 0 0

I'm now getting this in the logs. The exsisting PCs which are working are working on port 6002 ?

Really confused now.....

Any help will be grand :-)

RPC over HTTPS makes calls on port 6001, 6002, and 6004, although those should be internal calls only. The traffic actually comes in on port 443.

Checking my own logs, you should see calls to all three ports. If you are only seeing one then something isn't correct.

The first thing I would be looking to do is disable Outlook Anywhere on the server, then wait, then enable it again. That should make the registry changes be rewritten.

Simon.

Hi Again,
I tried what you advised this morning Simon and now i'm getting data flowing via the 6004 ports. I can still access exchange over the internet but still not for new profiles on PC's.

servername.domain.local:6004 443 domain\gary <local IP> MSRPC 200 0 0
servername.domain.local:6004 443 domain\gary <local IP> MSRPC 200 0 64

Any other ideas?

The only left to do is to remove the feature completely.
Disable Outlook Anywhere in Exchange 2007 and wait a few minutes for that change to be seen by Exchange.
Then use Add/Remove programs to remove the RPC proxy component.
Once removed, delete the /rpc and /rpc-with-cert virtual directories.
Run iisreset to write the change to the IIS metabase.
Wait.

Then reinstall the RPC Proxy component. After verifying that the virtual directories have been recreated, enable Outlook Anywhere in Exchange 2007 again.

If that still doesn't work, then I would have to suspect that the registry settings might not be written correctly, and that would require manual modification, but that shouldn't be required - it isn't something I have had to do as a regular thing.

Simon.
