In a virtual environment, I was enabling jumbo frames. When I enabled it on one vSwitch I lost connection to one of my host machines. I contacted vmWare and they tried to trouble shoot but they said I have to do a network setting reset. So I did but on the wrong host machine that my Primary DC was on. After the reset I had to quickly configure it again just to run the VMs during production time. Then I reset the second host that had the second DC. After completing the settings on it. I was not able to connect to my vCenter, VMware troubleshooted and realized that my DCs are not communication and my GC and active directory are not working. I am stumped and need thelp to get this resolved. I am willing to stay up late to get this fixed. I do not wnat my boss to get upset at me. The Strangely, the VMs are still runnning.
