How to remove a single Exchange 2010 CAS server from allowing Outlook to connect internally

exchange-2010

I'm trying to troubleshoot an issue with our Exchange 2010 setup and need to remove one of our CAS servers from allowing Outlook users to connect it internally. However, I'd still like for it to be functional with regards to OWA, ActiveSync, etc.

I'm fairly certain this needs to be done within EMC at Server Configuration > Client Access > Server Name, but I'm not quite sure what setting I need to change.

Thanks in advance!

I don't think you can do that in the EMC, but I believe it can be done with Set-RpcClientAccess (if you want to lockout specific clients) in the EMS or Remove-RpcClientAccess to disable it altogether. Make sure you know how to reconfigure it before doing it though.

Microsoft Reference for Set-RpcClientAccess

Okay, sorry to dismiss the earlier Server Fault message--it led me on the right track, at least. I called Dell support and had them walk me through disabling the performance features on the NIC, which resolved the issue. I think the key was disabling global chimney and receive side scaling, as I had tried most of the other steps as per the other Server Fault question posted. Of course none of these settings should cause problems, so maybe it's going to vary from server to server.

I also upgraded the driver version for the NIC, applied a BIOS patch and the latest Windows optional update rollup for Hyper-V issues, including a blue screen issue that we had experienced twice in the last week: KB2264080.

Here's the Dell support script I followed:

In a command prompt:

a. netsh int tcp set global chimney=disabled

b. netsh interface tcp set global rss=disabled

b. On each NIC inside the Broadcom Advanced Control Suite (BACS)

i. Disable IPv4 Checksum Offload

ii. Disable IPv4 Large Send Offload (LSO)

iii. Disable Receive Side Scaling (RSS)

. Uncheck the TCP Offload Engine (TOE) checkbox

v. Click Apply

Intel Configuration

a. Open Device Manager

b. On each Intel NIC in Device Manager, disable the following:

c. NOTE: Not every option is available or exist on the Advanced Tab.

i. Offload Receive IP Checksum

ii. Offload Receive TCP Checksum

iii. Offload TCP Segmentation

iv. Offload Transmit IP Checksum

v. Offload Transmit TCP Checksum

vi. IPV4 Checksum Offload

vii. Large Send Offload v2 (IPV4)

viii. Large Send Offload v2 (IPV6)

ix. Receive-Side Scaling

x. TCP Checksum Offload (IPV4)

xi. TCP Checksum Offload (IPV6)

In Windows Server 2008

                                                                                 1.      Start à Run à CMD 

                                                                                 2.      netsh interface tcp set global rss=disabled

a. netsh int tcp set global autotuninglevel=disable
