I have 4 Exchange virtual machine (vmwarE) servers SP3 RU1 and use Windows NLB
2 CAS servers
2 DAG servers
died (because I reverted to a snapshot during an upgrade) so I build a new server did a Setup /m:RecoverServer
to recover Exchange and kept the same name and IP.
This issue is when I have both CAS servers up some of my Outlook clients connections are very slow....... When I look in the Outlook clients connection the status says it is connecting via HTTPS not TCP/IP(as it should).
When I look at the Outlook connection status of users who's Outlook works fast the connection status is TCP/IP(as it should be).
When I shut down CAS Server1
and keep CAS Server2
on all my Outlook clients connect via HTTPS and are very slow..........
When I shut down CAS Server2
and keep CAS Server1
on all my Outlook clients connect very fast and connect via TCP/IP
This issue seems to be with CAS Server2 (the recovered Exchange server)
. I have configure Windows NLB as multicast and set the static ARP records to match the NLB MAC adddress.
I don't know what is missing form CAS Server2?
I found this not sure if this is related? I did not apply. See the part "One final step, on each of the NLB members run the following command to allow the NLB virtual IP address to be reachable from outside of the subnet that it resides in."
