i am using below command to change the windows7 desktop OS to domain, but it is not working.

$Domainchange = "Add-Computer -DomainName $domain -Credential $userid"

Invoke-VMScript -VM $vm -ScriptText $Domainchange -GuestUser gusername -GuestPassword gpwd -ScriptType Powershell

Is UAC enabled in that guest OS?

[satheeshsatz]

yes, i have enabled UAC,

rest of my commands are working, like renaming and changing IP

Could be, but this one requires UAC permission.
You can check by disabling UAC, and then testing your command again.
