I am using Exchange 2003 on a MS Windows 2003 server 32bit with only one organization in a domain environment.
A few weeks ago it started answer slowly for Outlook users telling "trying to retrive data from mail.domain.com server"
I have run Exchange Best Practices Analyzer tool to check for integrity and it found some critical issues like "system pages set too high" and "HeapDeCommitFreeBlock Threshold" not set.
Are these causing my slowness of the server or should I look for something different?
And how can I / should I fix these?
