kernel32.dll error

[dlrslvr]

Does somebody know what to do to fix the follow error:

Everytime I open Outlook 2000 and download email at the
end of the download I get a kernel32.dll error and have to
restart the computer to clear it otherwise it goes to dial
up instead of the cable modem to send and receive emails.
I am using Windows ME and have Norton Antivirus and
ZoneAlarn firewall installed.

Thanks in advance!
