We are currently having a problem with our exchange sever were the outlook clients are having problems connecting to it. However, at first it only started at peak hours but now is at random times of the day.
The one thing i have been wondering, if its the Qlogic card causing a lag on exchange.
Exchange is not throwing up errors in eventlogs, which normal for exchange.
Ive been though quite a few technet archcals about RPC errors and connection limits etc.. all seem to have made no difference.
Ive created another volume for a pagefile, so it has 2 pagefiles now. This has made no difference.
Our current setup:
Netapp 3020 Filler
Exchange 2003 Server - This boots from a Qlogic iSCSI card, all transaction logs and DBs are are on the netapp filler under different arrgratates.
HP XW Series PCs running a Gigabit ethernet.
