Agent Error? IOException in sending Request :: Connection refused: connect

Question

For the past couple of days, I have been running into the "IOException in sending Request :: Connection refused: connect" error. I am running 10.2.01 on Windows 2003R2.
Along with this error, the DB Control shows agent unreachable.
Is there anything that anyone knows that may have caused this issue?
Thank You in advance,
Jeff

Jhep,
Have you changed the timezone settings on the database server? Check emdctl.trc and see what it says. In the meanwhile, (a) stop dbconsole service, (b) execute emctl resetTZ agent and (c) restart dbconsole service.
Kindly should refer to the following Metalink Notes for a possible workaround:
bq. Metalink Note ID: 362888.1 "Startup Agent: EM Agent will not start due to Timezone mismatch (Daylight \\ Savings changes for Australia)" \\ Metalink Note ID: 409121.1 "Startup Agent: Agent Fails to Start due to Incorrect Timezone File Used as \\ Pointed by ORA_TZFILE" \\ Metalink Note ID: 388280.1 "Startup Agent: ORA-20233: Invalid agent name when running \\ mgmt_target.set_agent_tzrgn procedure in repository"
Lastly, see if any of the following post(s) are of any assistance to you:
bq. Oracle 10g EM DB console Host Preferred Credentials for Windows \\ Oracle 10g EM DB console Host Preferred Credentials for Windows \\ New Error -- Since DST 2007 \\ New Error -- Since DST 2007 \\ DST Patching for Grid Control Release 2 \\ Re: DST Patching for Grid Control Release 2
Hope this resolves the issue.
