Ok. These the steps that I took and it is still not working:
1)sudo /Library/StartupItems/SMC/smclient --stop (Note: There is a space after sudo and before --stop)
2) renamed the existing SyLink.xml to SyLinkold.xml
3) manually exported SyLink.xml from prod
4)sudo /Library/StartupItems/SMC/smclient --start (Note: There is a space after sudo and before --start)
It is still reporting to old test SEPM server.
Thanks,
