Hi, have two CAS server on active active configuration using NLB, and two malbox server. The CAS server's have the hub transport, and client access role's.
few days ago, one of the CAS server stop to response to the telnet, the firewall is down so isn't a port block issue. As a result of that, the other CAS server have the processor at 95%.
any ideas?

Restart the services or reboot the server? What troubleshooting steps have you done so far?

I rebooted the server, check the
services and are all up. In the event viewer this error appears almost one time in a day

Do you telnet ip of this server or server name of this server ?
According to your error , it is just dns issue not exchange.Terence Yu
