Notes from our Linux admin on what he did when WSManFault is gray + critical in the console from Certificate error. This was the only way we could fix this one quickly.

The cert failed because it was signed by opsmgr01 or opsmgr03 which is not a FQDN. Normally the search line of /etc/resolv.conf should have directed any dns search to the correct server but the file had been overwritten by NetworkManager. You can get around this by putting a search line in /etc/sysconfig/network-scripts/ifcfg-eth0. Here’s the procedure to fix

1. make sure “MS1” and “MS2” are pingable not as FQDNs
2 rpm -e
3. rm -rf /etc/opt/Microsoft/scx/* (necessary to remove cert)
4. reinstall scom through operations manager

If you leave out any of the above steps then it won’t work. If you are doing this in rhel5 you have to add the extra step of making sure the svcscom account has full access to all files in /etc/opt/Microsoft/scx/ssl

net stop HealthService
cd\
cd C:\Program Files\System Center 2012\Operations Manager\Server\Health Service State\Health Service Store
del *.* /F /Q
net start HealthService
