Got a strange problem with our Exchange Server (W2k SP4 - Exchange SP3) that I'm unable to fix.
Many clients are using Outlook with POP to get their mail from our server. When sending and receiving, the emails will send but they will only receive very slowly (too slow to use).
A reboot of the server seems to fix it for a half hour maybe before it slows down to a crawl again. Main problem is that I can't actually find anything wrong other than its slowed down a lot.
Clients running in Exchange mode seem OK, it seems to only be the POP access. No real errors in Event Log even with detailed POP logging on. No CPU or Network workload to speak of.
Any ideas at what it might be / how to find out whats wrong with it would be appreciated. Spent 10 hours looking at it and got nowhere .
