Cant start agent

Question

Hi!
The agent went down this weekend and refuses to start. I only get this when I try to start it:
E:\oracle\product\10.2.0\agent10g\bin>emctl start agent
Oracle Enterprise Manager 10g Release 3 Grid Control 10.2.0.3.0.
Copyright (c) 1996, 2007 Oracle Corporation. All rights reserved.
The Oracleagent10gAgent service is starting.......
The Oracleagent10gAgent service could not be started.
A service specific error occurred: 2.
More help is available by typing NET HELPMSG 3547.
Platform: Windows 2003
The NET HELP does not provide anything.
I have checked the different logs and nothing of use.
Any ideas?

Because Im such a nice guy, I will post the solution here :-)
I got good help from Oracle support.
We are using RAC, by the way.
First of all I had to delete all files located in:
E:\oracle\product\10.2.0\agent10g\sestows47.prg-dc.dhl.com\sysman\emd\state
E:\oracle\product\10.2.0\agent10g\sestows47.prg-dc.dhl.com\sysman\emd\upload
and
E:\oracle\product\10.2.0\agent10g\sestows47.prg-dc.dhl.com\sysman\log
After that, I was able to start the agent using:
emctl start agent
The agent are up and running this morning, but here are some solutions from Metalink if the problem occurs again:
Solution:
Article-ID: Note 434218.1
Title: Metric Collection error-Instance Health Check
initialization failed GIM-00104 LEM-00031 LEM-00033
1. Check if you have any hc_<sid>.dat file
ls -al $ORACLE_HOME/dbs/hc*
2. Stop the Database
3. Move all the hc_<sid>.dat file to hc_<sid>.dat file to hc_<sid>.dat_sic
4. Start the database
5. Change directory to the AGENT_HOME/bin directory.
Execute $emctl upload
Execute $emctl reload
The Metric collection error and errors in the emagent.trc will be gone.

UPDATE
======
Other solution is to disable the Healthcheck Metric For All Targets In One Shot
1. Stop the Agent with "emctl stop agent"
2. Edit the file $AGENT_HOME/sysman/admin/default_collection/instance.xmlp and change the section
<CollectionItem NAME="health_check" UPLOAD="NO" COLLECT_WHEN_DOWN="TRUE">
</CollectionItem>
to
<!--
<CollectionItem NAME="health_check" UPLOAD="NO" COLLECT_WHEN_DOWN="TRUE">
</CollectionItem>
-->
3. Startup the agent with "emctl start agent"
