Exchange possibly virtual memory fragmentation

I have an  DC Server 2000 standard with Exchange 2000  with 10 users.
Recently most of the workstations are recieving "trying to connect to exchange server" messages and things are REALLY slow as far as outlook response times.
I am getting this message about every 5 minutes.

I have followed numerous articles on the subject but cannot seem to get it fixed.
** I have increased the msExchESEParamCacheSizeMax to 1.3GB
** I have followed ALL the steps here
**Defragged, virus scan etc. installed the latest and greatest from the MS Updates/ Service packs
** I don't think i am a candidate for the /3GB switch since i am on 2000 standard, but there is debate....???

I have heard you guys have the answers.  Can anyone shed some light please?

EXBPA is a good point to start; else:
2003 SP2 has a fix which you can get seperately from PSS; you would need to call Microsoft for this...they dont charge for hotfixes.

A computer that is running Windows Server 2003 may use lots of pool memory

You don't have to pay, you just have to go separately to the Microsoft knowledgebase lookup page and look up the article numbers yourself.  All paying does (besides subsidizing, which is a great website with lots of good info on it) is allow those links to open automatically.

The Microsoft Knowledgebase search page is:
I would suggest running the Exchange best practises tool on the machine and see what that flags. You can download it form
