“System Extensions” not being registered

[coreybrett]

I am having trouble with some of the “System Extensions” not being registered. This morning the Conference, IVR & FAX extensions were all down. This has happened on several occasions.

I've looked threw the Windows Event log and I can not find anything that might indicate what happened.

Anyone have a guess?

Did you also look through the 3CX log?

Hi, what OS are you using and architecture (32 or 64).
Can you send me a personal email on [email protected].
Thanks and Regards.

Contacted user - it seems that since user moved from Hyper V to Physical machine the problem disappeared.
This shows that probably the hyper V loopback interface crashed and the virtual machine lost Network connectivity until windows or HV detected the problem and restarted the tcp stack.
