SEP client always error in one particular server ?

People,

I'm running Windows Server 2008 R2 as a VM in my production environment. All of them running good with the SEP client since v11 but this one particular VM, always stuck with the SEP client unable to get updates from the SEPM server ?

This is the error message:

Error logged daily:

The following boot-start or system-start driver(s) failed to load: SRTSP

I have make sure that I can ping the SEPM server from the affected VM and also it is on the same subnet hence there is no firewall.

This has been an ongoing issue since I install SEP cleint v11.0.6 and then upgraded to the latest 12.1 MP4.

Any help would be greatly appreciated.

Thanks,
