We have run the Exchange Best Practices Analyzer on our Exchange 2003 Server and received the following Critical Issue (the Exchange currently has 4GB RAM installed):
Server *.*.* has 1 GB or more of memory, accommodates 45 mailboxes, and the 'HeapDeCommitFreeBlockThreshold' parameter has not been set to 262144. Virtual memory may become quickly fragmented and system instability may occur.
I understand that to correct the issue requires the creation of a Registry Key (DWORD) with the value 0x00040000:
I wanted to ask if there is any real gain in enabling / creating this Registry Key bearing in mind that we have only 45 mailboxes and the Exchange sits at 1.88GB utilised RAM?
Many thanks in advance
