asked on

exchange

we have 1 mailbox server which uses 2 DC which in turn are on exchange server 1 and exchanger server 2. 1 dc is on CAS and Hub Server and other dc is on exchange server which has just EMC installed and is used as management server. both are in same forest

we see CPU hikes during morning hrs , It shows in task manager about high lsasse.exe as users log in during morning but my question is

why the other exchange server which is management server experiences cpu hikes

Amit

Check handles count for lsass.exe. If it is above 50K then you will see issue. Also see, which process is actually showing high CPU, when this issue occurs again.

I told earlier it is high lsasse.exe but what is the reason that other server experiences as this server is management server

Amit

Is this VM or Physical? And how many CPU and RAM assigned to this server.

it is physical 4gb ram 1 processor but the other exchange server should handle all the directory looks ups, how this server is getting into the picture

dc on exchanger server 1 which is cas and hub doesn't experience lsasse.exe hike but the management server does?

IS IT because both exchange server send LDAP at same time?
