Hi Frank Costa,
Could you check the SAP host agent? I think that requires a small upgrade. Also as I mentined earlier, could you check the DNS configuration set in IP-config?
Could you also check running the command in CMD R3trans -d & could you please check in services.msc whether the databse service is still running, if not then start the databse service from there & again start the sapmmc.
Also I would like to refer the similar issues faced by our friends,
sapmmc stays yellow when starting server
SAP Netweaver AS ABAP 7.02 (dispatcher turns grey and stops)
DISP+work.exe stopped working in SAP TRIAL version(FRESH installation)
Thanks,
Kaushik
