What "problem" are you referring to? Before you answer, have you seen this: http://www.petri.co.il/greylisting_in_exchange_2003.htm

In short - Exchange 2003 SP2 failes to re-queue messages sent to some servers that implement greylisting. This does not happen all the time (some messages go through but sometimes it fails). When the problem happens, those emails are hidden in the queue folder until the SMTP service is restarted, and the sender does not get an NDR nor Delay notification, even after those timeouts expire. Such messsages can remain "lost" for days or even weeks, until the SMTP service is restarted. After a restart of SMTP service, Exchange suddenly finds those lost emails, and retries to send them or returns NDR to the sender. Im experiencing this problem on 2 Windows 2k sp4servers with Exchange 2k3 sp2. There is a KB934709 with a hotfix to windows 2k3 SMTP service, but it doesnt install on Windows 2k server. The only workaround I have found that works on win2k is restarting the SMTP service each night. That doesnt fix the problem, but it flushes the queue folder and the sender gets a NDR.

I'm experiencing the same thing.I'm also running Exchange 2003 SP2 on Windows 2000 SP4, and can't seem to find a solution anywhere. What command can be used to restart the Information Store at the command line (so I can set it up as a scheduled task each night)?
