I have a stand-alone E3K Enterprise server on W3K Std Server, about 40 clients using OL3K, with multiple IS stores totalling about 100GB of info. We have been experiencing latency when users are accessing data through OL, especially our administrative users who access calendaring and contact information of our executives. I have looked at other posts and forums and have done some basic trouble shooting but haven't been able to specifically determine if it's the network or if it is the server that is the problem. Using perfmon on the E3K server RPC latency spikes at times when users have the delay, but all other counters seem to be okay in general.
The slowness has been here since our upgrade to E3K last year, but increased when we changed our IP phone system. I have used netmon to capture packets at the E3K server but really do not know what to look for to determine if the issue is network related.
Our IP phone system is on a separate VLAN but there is connectivity for voice mail to E3K using IMAP.
Any thoughts would be appreciated.
