memory setting for new installation

I'm set up a new Exchange 2003 EE on a server running Windows 2003 Standard
Edtion. My new server has 4 GB RAM. I'll add /3 gb /userva=3030 in
boot.ini. But I
m wondering if I need to modify the registry for
HeapDeCommitFreeBlockThreshold. Some articles said that it's not necessary
but monitor the performance of Exchage. Some said you should do it in the
first place. So, is it a good practice to do it with checking how Exchange
works first?

Thanks,

I wouldn't change it unless you see symptoms that indicate that it's
necessary.

I got event id 9665 without it. After the registery change for
HeapDeCommitFreeBlockThreshold it disappeared. Does that mean I do need it?
I haven't created any mailbox on this server yet. No user access at all.

You should set heapdecommitfreeblockthreshold to 0x40000. If you run exbpa,
it'll tell you this.
