windows service question

hey all,

i'm doing a simple walkthrough article on windows services and am having a
problem.

i have a virtual pc i'm working on which has an smtp server that i easily
tested and works. well, the windows service program, all it does is use the
timer elapsed event to send out an email, this is the part that doesn't work.

i looked in the event viewer for System log file and it shows this:

Event Type: Error
Event Source: smtpsvc
Event Category: None
Event ID: 402
Date: 2/2/2006
Time: 2:12:44 PM
User: N/A
Computer: CS1L1-201
Description:
Virtual Server 1: 127.0.0.1 maximum number of connections has been reached.

Any ideas?
