new distribution group creation error

Hello,

I am trying to create new distribution group using exchange management shell  but its giving an error " A positional parameter cannot be found that accepts argument '-Type' ".Same command runs successfully on other exchange 2010 server .

Command I am using is 

new-DistributionGroup -Name 'my_test1' -OrganizationalUnit 'ou=a.test,dc=testlab.l' -DomainController 'testlab.l' -Type 'Distribution' -Alias 'forcheck'|select distinguishedName

So,is there any configuration setting required for this or anything else that is causing this.

Thanks,

S.D
