re: OCS 2007 R1/R2 Remote Access Configuration Guide

shah — Thu, 23 Sep 2010 08:19:01 GMT

what if we have a single AD & multiple sip .. then how will we restrict remote administrators so that they can create only respective sip for respective users.

e.g.

one ad

we have single AD ... and 6 differnt universities but all are on same AD... each uni has its own UPN.. how can we restrict these six universities (uni) admin .. which will connect remotely and they shud be able to make users of their respective upn only.. uni1 must not be able to mess with uni2 sip... intentionally or unintentionally ...

please guide! thanking u in advance

Ok - I answered my own question!

For others struggling to find the dialog box shown in fig. 1.2:

On your edge server goto: start->run-> type in compmgmt.msc

At the bottom of the left hand pane you should notice a new entry - Office communications server. Right click it, choose properties, edge interfaces, click configure next to the A/V edge server section.

Sounds really obvious now, but I completely missed this simple step for days because I kept going to server manager instead!

I have the same problem but I cannot find the configuration dialog that you show in figure 1.2. I have been through all the administration and config screens I can find but cannot find the option "External IP Address is translated by NAT" ANy pointers in the right direction would be much appreciated!

Same problem in a single server topology

Hi all,

I've got exactly the same problem as the one described here.

But in my case, I only have a single test server (with just 1 NIC) that handles all the roles, so there is no edge server.

The problem is that when I go to the A/V Conferencing server properties, I have fewer options: I do not have the "External IP address is translated by NAT" checkbox and there is no place for Media port range for example.

How can I figure this out?

Is there any doc describe A/V call flow between External User and (External or Internal) user in OCS 2007 R2?

Hi All,

Just got the things work!!!

Here is my settings.

*** I have no dns access from the DMZ where the consolidated edge server placed ****

1. I use the private ip of av edge external nic in figure 1.2 instead of the public ip.........

2. In the av edge server host file, add entry to resolve the av edge external FQDN to public ip of av edge. In Rick's example, it should be <av.contoso.com 63.123.155.5>.

3. Most important.......... Add a A record in the inside DNS server to resolve the internal FQDN of av edge server "av edge internal nic ip". In Rick's example, it should be <ocsedge.contoso.net 172.25.33.20>.

A very obvious symtop is before I make change in Point 3, any audio or video calling takes few seconds before the pop up appear on the callee side, no matter the caller is insider or outsider.

After Point 3, all callings appear at once at the callee side.

Hope this help all other brothers.....

Notmen.

Hi Rick,

Sorry there is typo on the previous post.

We are very confused with figure 1.2. I CAN NOT select the public IP address from the list, because the list is about the nic ip of the av edge server.

Please please help.............
