I have powershell version 4.0 and Power CLI version 6.5 Release build 4624819. If I run one line command like  “Get-VMHostNetwork -VMHost $esx | Set-VMHostNetwork -DomainName $domainname -DNSAddress $dnspri , $dnsalt -Confirm:$false” it runs ok. But I have to make few change for 100+ servers so I have created below script. But, problem is PowerCLI is not understand the EACH loop or variables. Even if I put some variable in PowerCLI like $Test = I am Arif then , it does not understand what is $Test. I then imported Vmware.PowerCLI module to powershell and same problem there. Can someone pls help me urgently.
